Q 2: Is it permissible to
wipe the face with one's hands after Du`a' (supplication) following Salah (Prayer)?
It is better to refrain from doing so because all the Hadith narrated in this regard (Part No. 24; Page No. 218) are Da`if (weak).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
