Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both), he says: A man came to the Noble Prophet (peace and blessings of Allah be upon him) and said: O Messenger of Allah! Which people are most beloved to Allah Almighty and which deeds are most liked by Allah Almighty? The Messenger of Allah (peace and blessings of Allah be upon him) said: "The people most beloved to Allah Almighty are those who are most beneficial to other people, and the most beloved deeds to Allah Almighty are: to bring happiness to a Muslim brother, to remove some difficulty from him, to pay off his debt, and to feed him. (See) For me to walk with a brother to fulfill his need is more beloved than performing i'tikaf in this Masjid Nabawi for a month. (And remember that) whoever restrains his anger, Allah Almighty will conceal his faults, and whoever swallows his anger despite having the power to act on it, Allah Almighty will fill his heart with hope on the Day of Resurrection. Whoever walks with his brother to fulfill his need, Allah Almighty will keep him firm on the Day when feet will slip, and bad character destroys deeds just as vinegar spoils honey."
