Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him): He says, the Prophet (peace and blessings be upon him) was teaching the companions matters of religion when suddenly their eyes were raised upwards. The Prophet (peace and blessings be upon him) asked: "What is it that has caused your eyes to be raised upwards?" They said: We looked at the moon. The Prophet (peace and blessings be upon him) said: "What will your condition be at that time when you will see Allah the Exalted clearly?"

Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, Allah does not look at your bodies, your forms, or your wealth; rather, He looks at your hearts and your deeds."

It is narrated from ‘Amir bin Sa’d, he says that Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) was among his camels when his son ‘Umar came to him. When Sa’d saw him, he said:“I seek refuge with Allah from the evil of this rider.”Then he (‘Umar) dismounted and said:“You have become devoted to your camels and goats and have separated yourself from the people while they are disputing about the government.”Sayyiduna Sa’d struck his chest and said:“Be quiet! I heard the Messenger of Allah (peace and blessings be upon him) say: ‘Indeed, Allah loves the pious, self-sufficient, and obscure servant.’”

Kathir bin Aslami narrated this from Mutlib, who narrated from ‘Umar bin Sa’d, who narrated from his father that he said:“My son came to me, and I said to him (in response to his words): ‘My son! Are you inviting me to become a leader in the turmoil? By Allah! (I will not go until) I am given such a sword that if I strike a Muslim with it, it does not hit him, and if I strike a disbeliever with it, it kills him. I heard the Messenger of Allah (peace and blessings be upon him) say... (the above-mentioned hadith was mentioned).”

There is a narration related to Allah Almighty’s statement,“And when the girl who was buried alive will be asked,”from Sayyiduna Umar bin Khattab (may Allah be pleased with him). He says: Sayyiduna Qais bin Asim (may Allah be pleased with him) came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! In the days of ignorance, I buried alive eight of my daughters. The Prophet (peace and blessings be upon him) said:“For each one of them, free a slave.”He said: I am a man of camels. The Prophet (peace and blessings be upon him) said:“If you wish, then sacrifice one camel for each one.”

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "Whoever kills himself with a spear, he will continue to stab himself with it in Hell.

Sayyiduna Jundub bin Abdullah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "There was a man among those before you who was wounded and could not bear the pain of his wound, so he took a knife and cut his hand. The blood kept flowing until he died. Allah the Exalted said to him: My servant has hastened in the matter of his soul before Me, so I have made Paradise forbidden for him."

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said:“Indeed, Allah does not wrong a believer even in regard to a single good deed. The believer is rewarded for his good deeds in this world, and he will also be rewarded in the Hereafter. As for the disbeliever, the good deeds he does for Allah are recompensed for him in this world itself. Therefore, when he meets Allah on the Day of Resurrection, he will have no good deed left for which he may be rewarded.”

Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) was asked: "Which deed is the best?" He (peace and blessings be upon him) replied: "That you bring happiness to your Muslim brother, or pay off his debt, or feed him."

Sayyiduna Nu’man bin Bashir (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said:“Indeed, there is a piece of flesh in the body of the son of Adam; if it is sound, the whole body is sound, and if it is corrupt, the whole body becomes corrupt. Behold, that (piece) is the heart.”
