Sayyiduna Khalid bin ‘Adi Juhani (may Allah be pleased with him) says that I heard the Messenger of Allah (peace and blessings of Allah be upon him) say:“If something is received by someone from his brother, he should accept it and not reject it, provided that he neither asked for it nor was greedy or covetous for it, because it is sustenance which Allah, the Exalted, has granted him.”
