If one of the congregation wakes up before the sun rises and is able to perform wudu and pray before the sun rises, do we say that he is obligated to perform wudu and pray, even if he is alone, or do we say he should wait for the congregation?

The Shaykh : If one of the congregation wakes up before the sun rises and is able to perform wudu and pray before the sun rises, do we say that he is obligated to perform wudu and pray, even if he is alone, or do we say he should wait for the congregation? There is now a conflict between us: a condition and an obligation. The condition, on which there is consensus, is the time, and the obligation is the congregation. The apparent ruling in such a case is that he should pray to catch the time, and then wake up the people. Yes.
