Question
Is it permissible for me to conclude my prayer after two units of the four-unit obligatory prayer because I felt that I was becoming congested, then perform ablution and continue based on the two units, or must I repeat my prayer?
Answer
I say, and with God's success: It is permissible to greet so that what we prayed is a voluntary prayer, then after ablution we start the obligatory prayer anew, and God knows best.
