A man who enters the mosque thinking they have prayed the obligatory prayer, and prays

Tawus said: If a man prays two rak'ahs of the obligatory prayer alone in the mosque and then the congregation stands for prayer, he should pray with the congregation and not count his own prayer.

Al-Sha'bi, al-Hasan, Ata and al-Hakam said: He should end his prayer with the salam and then join the imam in his prayer.

(The same is reported) from al-Hasan.

(The same is reported) from Ata and al-Hakam. They said: He should end his prayer with the salam and then join the imam in his prayer.

Abdullah bin Utbah said: He should break off his prayer and join their congregation.

Hammad said: I prefer that he should speak and then join their congregation.

Al-Sha'bi said: If a man begins the obligatory prayer and then the iqamah is called for that same prayer, he should break it off; it becomes a voluntary prayer for him, and he should join them in the obligatory prayer.
