The rights of Muslims over one another: love, advice, help and enjoining good.
On the authority of Tameem ibn Aus ad-Daree (ra): The Prophet (ﷺ) said, “The deen (religion) is naseehah (advice, sincerity).” We said, “To whom?” He (ﷺ) said, “To Allah, His Book, His Messenger, and to the leaders of the Muslims and their common folk.”
On the authority of Abu Hamzah Anas bin Malik (may Allah be pleased with him) — the servant of the Messenger of Allah (peace and blessings of Allah be upon him) — that the Prophet (peace and blessings of Allah be upon him) said: None of you [truly] believes until he loves for his brother that which he loves for himself. [Al-Bukhari]
On the authority of Abu Hurayrah (may Allah be pleased with him), that the Messenger of Allah (peace and blessings of Allah be upon him) said: Let him who believes in Allah and the Last Day speak good, or keep silent; and let him who believes in Allah and the Last Day be generous to his neighbour; and let him who believes in Allah and the Last Day be generous to his guest. [Al-Bukhari]
On the authority of Abu Hurayrah (may Allah be pleased with him) who said: The Messenger of Allah (peace and blessings of Allah be upon him) said, “Every joint of a person must perform a charity each day that the sun rises: to judge justly between two people is a charity. To help a man with his mount, lifting him onto it or hoisting up his belongings onto it, is a charity. And the good word is a charity. And every step that you take towards the prayer is a charity, and removing a harmful object from the road is a charity.” [Al-Bukhari]
On the authority of Abu Sa’eed al-Khudree (may Allah be pleased with him), that the Messenger of Allah (peace and blessings of Allah be upon him) said: There should be neither harming (darar) nor reciprocating harm (dirar). A hasan hadeeth related by Ibn Majah, ad-Daraqutnee and others as a musnad hadeeth. It was also related by Malik in al-Muwatta in mursal form from Amr bin Yahya, from his father from the Prophet (peace and blessings of Allah be upon him), but leaving Abu Sa’eed from the chain. And it has other chains of narrations that strengthen one another
On the authority of Abu Sa`eed al-Khudree (may Allah be pleased with him) who said: I heard the Messenger of Allah (ﷺ) say, “Whosoever of you sees an evil, let him change it with his hand; and if he is not able to do so, then [let him change it] with his tongue; and if he is not able to do so, then with his heart — and that is the weakest of faith.”
On the authority of Abu Hurayrah (may Allah be pleased with him) who said: The Messenger of Allah (peace and blessings of Allah be upon him) said, “Do not envy one another, and do not inflate prices for one another, and do not hate one another, and do not turn away from one another, and do not undercut one another in trade, but [rather] be slaves of Allah and brothers [amongst yourselves]. A Muslim is the brother of a Muslim: he does not oppress him, nor does he fail him, nor does he lie to him, nor does he hold him in contempt. Taqwa (piety) is right here [and he pointed to his chest three times]. It is evil enough for a man to hold his brother Muslim in contempt. The whole of a Muslim is inviolable for another Muslim: his blood, his property, and his honour.”
On the authority of Abu Hurayrah (may Allah be pleased with him), that the Prophet (peace and blessings of Allah be upon him) said: Whoever removes a worldly grief from a believer, Allah will remove from him one of the griefs of the Day of Resurrection. And whoever alleviates the need of a needy person, Allah will alleviate his needs in this world and the Hereafter. Whoever shields [or hides the misdeeds of] a Muslim, Allah will shield him in this world and the Hereafter. And Allah will aid His slave so long as he aids his brother. And whoever follows a path to seek knowledge therein, Allah will make easy for him a path to Paradise. No people gather together in one of the Houses of Allah, reciting the Book of Allah and studying it among themselves, except that sakeenah (tranquility) descends upon them, and mercy envelops them, and the angels surround them, and Allah mentions them amongst those who are with Him. And whoever is slowed down by his actions, will not be hastened forward by his lineage.
