Starting work early in the morning
Starting work early in the morning has been highly lauded in the hadith corpus. Our eternally blessed Prophet has said, "Oh Allah! Grant abundance to my ummah in its works of early morning."
The blessed Prophet has also prohibited sleeping just after fajr prayers prior to sunrise and has called it a source of poverty (Ibn Maja). Once, upon seeing Fatimah - may Allah be pleased with her - sleeping just after fajr, he woke her up and told her never to sleep at that time (Targhib, p. 191, vol. 3, ref. Behaqi)
