Abu Khaldah (may Allah have mercy on him) said: I heard Sayyiduna Anas bin Malik (may Allah be pleased with him) when Yazid al-Dabbi (may Allah have mercy on him) called out to him on a Friday: "O Abu Hamzah! You attended prayer with the Prophet (peace and blessings be upon him) and you have attended prayer with us; so how did the Prophet (peace and blessings be upon him) pray the Friday prayer?" When it was very cold, he would pray the Friday prayer early, and when it was very hot, he would delay the prayer to a cooler time.
