Instead of performing Tahyatul Musjid, is it permissible to engage in Tilaawat of the Qur‟aan and in Thikr?

Answer

The two raka'ts Tahyatul Musjid are thousands of time superior and of greater merit than your personal thikr. It is incumbent to first perform this Salaat, then engage in your personal thikr. You should not accord preference to your personal act over a Sunnat ibaadat.
