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 (a.s.), 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.’”

6. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following: “Abu ’Abd Allah (a.s.), once was asked about a man who has missed performing Salah (prayer) during the day. When is he required to perform the compensatory prayer for such Salah (prayer)? He (the Imam) said, ‘He can do whenever he wants. He can perform them after al-Maghrib or after al-‘Isha.”

7. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Safwan ibn Yahya from al-‘Ala’ from Muhammad ibn Muslim who has said the following: “I once asked abu ‘Abd Allah (a.s.), about a man who misses Salah (prayer) to be performed during the day. He (the Imam) said, ‘He can perform them whenever he wants. He can perform them after al-Maghrib or after al-‘Isha’.’”

8. Muhammad ibn Yahya has narrated from Muhammad ibn ’Isma‘il al-Qummiy from Ali ibn al-Hakam from Sayf ibn ‘Amirah in a marfu‘ manner who has said the following: “’Amir al-Mu’minin once passed by a man who was performing al-Duha’ (optional Salah (prayer) at noontime before Zawal (declining of the sun toward the west at noontime) in Masjid of al-Kufah. He (’Amir al-Mu’minin) poked his side with his whip (handle) and said, ‘You cut the throat of the Salah (prayer) of repenting people, may Allah cut your throat.’ He asked, ‘Must I omit it? He (the Imam) said that ’Amir al-Mu’minin said, “Have you seen the one who forbids a servant who performs Salah (prayer)” (96:9,10) he added.’ Abu ‘Abd Allah (a.s.), then said, ‘The denial of Amir al- Mu’minin is sufficient prohibition to perform such Salah (prayer).”’ (’Amir al-Mu’minin meant that it is not permissible to prohibit Salah (prayer) but Salah (prayer) of a prescribed time performed before its time is not a Salah (prayer). (It seems the man performed the optional Salah (prayer) soon after Zawal (declining of the sun toward the west at noontime) before its due time).
