It is narrated from Sayyiduna Mu'adh bin Anas al-Juhani (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Shall I not tell you why Allah Almighty made Ibrahim (peace be upon him) His faithful Khalil (intimate friend)? Because whenever he reached the morning or the evening, he would recite: 'So glorify Allah when you reach the evening and when you reach the morning' - until he completed the verse."
