Hadith.1377 - Umar ibn Hanzalah said to Imam Jafar ibn Muhammad Al-Sadiq (as):
"I have spent eighteen nights intending to rise (for the night prayer) but did not get up. Should I then pray at the beginning of the night?"
He (as) replied: "No, make it up during the day, for I dislike it becoming a habitual practice."
