By your order, it was taken out, then the Prophet (peace and blessings be upon him) sprinkled water on that place with his blessed hand. In the evening, Sayyiduna Jibreel came; he came to meet you. The Prophet (peace and blessings be upon him) asked him: You had promised me that you would come to meet me last night.
