It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that a man came to the Messenger of Allah (peace and blessings be upon him) and said: "O Prophet of Allah, I have relatives with whom I maintain ties while they cut me off, and I treat them well while they treat me badly." He (peace and blessings be upon him) said: "If the matter is as you say, then there will always be with you a helper from Allah, the Mighty and Majestic, against them."
