Hadith 1123
اذا ذكر الخليل و ذكرت فصلوا عليه ثم صلوا على واذا ذكر الأنبياء فصلو على ثم عليهم
"When the Friend of Allah (that is, Ibrahim, peace be upon him) and I are mentioned, then (first) send blessings upon him and then upon me; and when (other) prophets are mentioned, then (first) send blessings upon me and then upon them."
