It is narrated from Sayyiduna Amr bin Taghlib (may Allah be pleased with him) that some wealth came to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) gave to his people and deprived others. It reached him (peace and blessings be upon him) that the people had objected to this, so he (peace and blessings be upon him) said: "I give to one man and leave another, and the one whom I leave out is dearer to me than the one whom I give. I give wealth to those in whose hearts there is anxiety, alarm and impatience, and I leave out those whose hearts Allah has made free of need." Among them was Sayyiduna Amr bin Taghlib (may Allah be pleased with him). Sayyiduna Amr bin Taghlib (may Allah be pleased with him) says that these words of the Prophet (peace and blessings be upon him) were dearer to me than even red camels.
