It is narrated from Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) that the supplication of a religious brother for his religious brother is accepted.

Narrated from Sayyiduna Safwan bin Abdullah bin Safwan (may Allah be pleased with him), and in his marriage was Darda, the daughter of Sayyiduna Abu Darda (may Allah be pleased with him). He says: I came to them in Syria, and in the house was Sayyida Umm Darda (may Allah be pleased with her), while Sayyiduna Abu Darda (may Allah be pleased with him) was not present there. Sayyida Umm Darda (may Allah be pleased with her) said: Are you going for Hajj this year? I replied: Yes! She said: Then pray for good for us as well, because the Prophet (peace and blessings of Allah be upon him) used to say:“Indeed, the supplication of a Muslim for his brother in his absence is surely accepted. When he supplicates, an angel is appointed at his head. Whenever he prays for good for his brother, the angel says: Ameen, and for you the same.”He says: Then I met Sayyiduna Abu Darda (may Allah be pleased with him) in the market, and he said the same thing and narrated this hadith from the Prophet (peace and blessings of Allah be upon him).

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that a man made a supplication: "O Allah, forgive only me and Muhammad (peace be upon him)." The Prophet (peace be upon him) said: "You have withheld your supplication from many people."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that I heard the Prophet (peace and blessings of Allah be upon him) seeking forgiveness in one gathering a hundred times in this way: "O Lord! Forgive me, accept my repentance, and have mercy on me. Indeed, You are the Acceptor of repentance, the Most Merciful."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both), he said: I supplicate to Allah Almighty in all my affairs, even in such matters that He grants ease in the movement of my mount. To the extent that I see in it that which pleases me.

It is narrated from Sayyiduna Umar (may Allah be pleased with him) that he used to say in his supplication: O Allah! Cause me to die among the righteous, and do not leave me behind with the wicked, and join me with the good people.

It is narrated from Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) that he used to frequently supplicate:“O Allah! Rectify our affairs, guide us to the path of Islam, grant us deliverance from darkness into light, keep us away from all kinds of indecency and evil, both outward and inward, and bless our ears, our eyes, our hearts, and our wives and children. And accept our repentance, indeed You are the Acceptor of repentance, Most Merciful. Make us among those who are grateful for Your blessings, who praise them, and who acknowledge them, and complete Your favor upon us.”

It is narrated from Thabit (may Allah have mercy on him) that whenever Sayyiduna Anas (may Allah be pleased with him) prayed for any of his brothers, he would say: "May Allah make him deserving of the prayers of the righteous people who are neither oppressors nor sinners, who stand in prayer at night and fast during the day."

It is narrated from Sayyiduna Amr bin Huraith (may Allah be pleased with him), he says that my mother took me to the service of the Prophet (peace and blessings of Allah be upon him), so the Prophet (peace and blessings of Allah be upon him) passed his hand over my head and prayed for my sustenance.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that it was said to him that some of your brothers have come to you from Basra so that you may pray for them. Sayyiduna Anas (may Allah be pleased with him) was at the place of Zawiyah in those days. Sayyiduna Anas (may Allah be pleased with him) prayed as follows: O Allah! Forgive us, have mercy on us, grant us goodness in this world and the Hereafter, and save us from the punishment of the Fire. When they requested more supplication, Sayyiduna Anas (may Allah be pleased with him) again prayed in the same way and said: If you have received this, then you have received the goodness of this world and the Hereafter.
