Musannaf Ibn Abi Shaybah

Hazrat Hammad says that whoever misses one rak'ah should make it up, and in it, he should perform the same actions that the Imam performs in the first rak'ah.

Hasan says that in the Eid prayer, whichever rak‘ah one catches, he should say the takbeerat in it, and for whichever is missed, he should make it up in such a way that in the second rak‘ah he says the takbeerat just as the imam does.
