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 , 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.”
