Musannaf Ibn Abi Shaybah

Hazrat Abdur Rahman bin Abi Laila narrates that when the four rak'ahs before Zuhr would be missed by the Holy Prophet (peace and blessings be upon him), he (peace and blessings be upon him) would offer them later.

It is narrated about Ibrahim that when he missed the first four rak'ahs of Zuhr, he would perform them later.

Hazrat Amr bin Maymoon narrates that if a person misses the four rak'ahs before Zuhr, he should make them up after the two rak'ahs (after Zuhr). And it is mentioned as the saying of (Imam) Abu Hanifa that: He will neither perform those four rak'ahs nor make them up.
