The Prophet, peace be upon him, said: "The Book of Allah: It is the Rope of Allah that has been extended down from the heavens to the earth." (Ibn Jarir, Qurtubi)

Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (PBUH) said, "Three are the signs of a hypocrite: When he speaks, he lies; when he makes a promise, he breaks it; and when he is trusted, he betrays his trust.''
[Al-Bukhari and Muslim].

Another narration adds the words: "Even if he observes Saum (fasts), performs Salat (prayer) and claims to be a Muslim.''

Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (PBUH) never found fault with food. If he had inclination to eating it, he would eat; and if he disliked it, he would leave it.
Al-Bukhari and Muslim].

Commentary: This Hadith throws light on the Prophet's excellent manners which ought to be followed by all Muslims. It is a deplorable state of affairs that when we find a dish a bit unsavoury, we lose our temper and create quite a scene in the house. May we follow the excellent example of our Prophet (PBUH)!

Abu Umamah (May Allah be pleased with him) reported: I heard the Messenger of Allah (PBUH) saying, "Read the Qur'an, for it will come as an intercessor for its reciters on the Day of Resurrection.''
[Muslim].

Commentary: This Hadith tells the excellence of reciting the Qur'an and acting upon its injunctions. Intercession (in this Hadath) means that the Qur'an will be endowed with the power of speech by Allah and it will request Allah to forgive the sins of its reciters who acted upon its teachings. Allah will accept the request of the Qur'an, as signified in other Ahadith.

`Abdullah bin Salam (May Allah be pleased with him) reported: I heard the Messenger of Allah (PBUH) saying, "O people, exchange greetings of peace (i.e., say: As-Salamu `Alaikum to one another), feed people, strengthen the ties of kinship, and be in prayer when others are asleep, you will enter Jannah in peace.''
[At-Tirmidhi].

Commentary: All these habits and practices are indispensable to a believer because each one of them leads to Jannah with the first people to enter it without being punished in Hell first

Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (PBUH) said, "The believers who show the most perfect Faith are those who have the best behaviour, and the best of you are those who are the best to their wives".
[At-Tirmidhi].

Abu Dharr (May Allah be pleased with him) reported: The Prophet (PBUH) said, "Do not belittle any good deed, even meeting your brother (Muslim) with a cheerful face".
[Muslim].

Commentary: We learn from this Hadith that meeting somebody cheerfully is also a virtue for two reasons. Firstly, it is a sign of good manners. Secondly, it creates affection and friendship among the Muslims which is a meritorious act.

Ibn Abbas (May Allah be pleased with them) said: One day, I was riding behind the Prophet (PBUH) when he said, "O boy! I will instruct you in some matters. Be watchful of Allah (Commandments of Allah), He will preserve you. Safeguard His Rights, He will be ever with you. If you beg, beg of Him Alone; and if you need assistance, supplicate to Allah Alone for help. And remember that if all the people gather to benefit you, they will not be able to benefit you except that which Allah had foreordained (for you); and if all of them gather to do harm to you, they will not be able to afflict you with anything other than that which Allah had pre-destined against you. The pens had been lifted and the ink had dried up".
[At-Tirmidhi].

Another narration is: Messenger of Allah (PBUH) said, "Safeguard the Commandments of Allah, you will find Him before you. Remember Him in prosperity and He will remember you in adversity. Be sure that which you miss, was not to hit you; and what hits you, was never to miss you. Remember that the Help of Allah is obtained with patience, and relief emerges after distress, prosperity follows adversity, and hardship is followed by ease".

Commentary:
1. No one has the power to change the Decision of Allah.

2. Whatever trouble one has to suffer in this world, it does not last for ever. Every trouble is followed by prosperity, pleasure and happiness.

3. One should never ask other than Allah anyone's help in supernatural way because it amounts to ascribing partnership with Allah. If a person is mindful of the Rights of Allah, then Allah, in return takes care of his needs and helps him.

Sahih Bukhari
Volume 6, Book 61, Number 547:
Narrated Sahl bin Sad:

A lady came to the Prophet and declared that she had decided to offer herself to Allah and His Apostle. The Prophet said, "I am not in need of women." A man said (to the Prophet) "Please marry her to me." The Prophet said (to him), "Give her a garment." The man said, "I cannot afford it." The Prophet said, "Give her anything, even if it were an iron ring." The man apologized again. The Prophet then asked him, "What do you know by heart of the Qur'an?" He replied, "I know such-and-such portion of the Qur'an (by heart)." The Prophet said, "Then I marry her to you for that much of the Qur'an which you know by heart."

Narrated 'Aisha (Radhiallaho anha):
Once the Prophet (sallallaahu 'alaihi wasallam) came while a
woman was sitting with me. He said, "Who is she?" I replied,
"She is so and so," and told him about her (excessive) praying.
He said disapprovingly, "Do (good) deeds which is within your
capacity (without being overtaxed) as Allah does not get tired
(of giving rewards) but (surely) you will get tired and the
best deed (act of Worship) in the sight of Allah is that which
is done regularly."

Bukhari Vol. 1 : No. 41

Shahr bin Haushab reported: I asked Umm Salamah (May Allah be pleased with her), "O Mother of the Believers! Which supplication did the Messenger of Allah (PBUH) make frequently when he was in your house?'' She said: "He (PBUH) supplicated frequently: `Ya muqallibal-qulubi, thabbit qalbi `ala dinika (O Controller of the hearts make my heart steadfast in Your religion).''
[At-Tirmidhi].

Commentary: Steadfastness in religion is the conduct of great men, which cannot be acquired without the special Grace of Allah. There occur many turns in a person's life when he becomes slack or negligent in religious matters or when he deviates from the course prescribed by religion. This prayer has outstanding importance for such people who are faced with such a situation. They should recite this prayer very frequently. In fact they should make its recitation a permanent feature.

On the authority of Abu Hurairah, who said: the messenger of Allah said:

Allah the Almighty has said: "Who soever shows enmity to a friend of Mine, I shall be at war with him. My servant does not draw near to Me with anything more loved by Me than the religious duties I have imposed upon him, and My servant continues to draw near to Me with supererogatory works so that I shall love him. When I love him I am his hearing with which he hears, his seeing with which he sees, his hand with which he strikes, and his foot with which he walks. Were he to ask [something] of Me, I would surely give it to him and were he to ask Me for refuge, I would surely grant him it."
