Musnad Ahmad 25:111

Jarir narrated to us, from Qabus, from his father, from Ibn Abbas: "The Messenger of Allah, peace and blessings of Allah be upon him, was in Makkah, then he was commanded to emigrate. And there was revealed to him: 'And say, "My Lord, cause me to enter a sound entrance and to exit a sound exit and grant me from Yourself a supporting authority."'" [Al-Isra: 80]
