It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once the Prophet (peace and blessings be upon him) sent a silk garment to Sayyiduna Umar (may Allah be pleased with him). Then, when he saw it on Sayyiduna Umar’s body, he said: I did not send it to you for wearing, because in this world it is the clothing of those who have no share in the Hereafter. I sent it to you so that you may sell it and benefit from it.
