2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Ali ibn al-Nu’man from Ishaq ibn ‘Ammar who has said the following: “It is narrated to me from Abu ‘Abdillah عليه السلام who has said that once a man came to the Holy Prophet and said, ‘O Messenger of Allah, my family has refused to do anything for me but to cut off and abuse me, and I also want to reject them.’ He (the Messenger of Allah) said, ‘If you do so, Allah will reject all of you.’ He then asked, ‘What should I do?’ He (the Messenger of Allah) said, ‘Maintain good relations with whoever cuts you off, give to those who deprive you, and forgive those who do injustice to you. If you do this, you will have support for this from Allah.’”
