Ruling on working at night

The questioner : How are you, my Shaykh?

The Shaykh : Welcome.

The questioner : Is there anyone with you, O our Shaykh?

The Shaykh : Yes, please go ahead.

The questioner : I work at night and my rest is during the day, and I catch up...

The Shaykh : If you do not miss the prayers at their prescribed times, first, and do not miss the congregations, second, then there is no harm, provided you cannot find work to do during the day.

The questioner : ... .

The Shaykh : May Allah guide you. Say "Ameen." I think you did not understand the answer. If you do not miss any prayer at its prescribed time, first, and then you do not miss attending the prayer in the mosques of the Muslims, second, and then you are unable to find work during the day, third, with these conditions it is permissible. If any of these conditions is not met, it is not permissible. Did you understand? Say, if Allah wills. And where is the preacher?

The questioner : The preacher? I don't know...

The Shaykh : Let us go, we need to leave.
