A man praying alone: does he say the takbir or not?

Al-Hasan said: Whoever prays alone, or prays in congregation, or prays a voluntary prayer, should say the takbirs.

Ibrahim said: He is to say the takbirs only after a prayer in congregation.

Hammam said: I saw Qatadah pray alone during the days of Tashriq, and he said the takbirs.

Al-Sha'bi said: Say the takbir in voluntary prayer too, even if you are praying alone.

Mujahid said: During the days of Tashriq the takbirs are to be said after every obligatory and voluntary prayer.

Mujahid said: On the Day of Sacrifice (Yawm al-Nahr), the early generations used to say the takbirs after the two rak'ahs.
