Performing Optional Salah (Prayer) before or after, Compensatory prayer for them and Salah (prayer) of al-Duha’

5. Muhammad ibn Yahya has narrated from ‘Abd Allah ibn Muhammad from Ali ibn al-Hakam from Aban ibn ‘Uthman from ’Isma‘il al-Al-Ju‘fiy who has said the following: “Abu Ja’far عليه السلام, has said, ‘The best compensatory prayer for a Salah (prayer) missed is the compensatory prayer during the night for what is missed during the night and what is missed during the day is made during the day.’ I then said, ’So there will be two al-Witr in one night.’ He (the Imam) said, ‘No, there will not be two al-Witr.’ I then said, ‘Why then do you instruct me to perform two al-Witr in one night?’ He (the Imam) said, ‘One of them is a compensatory prayer for what is missed.’”
