Question:
May Allah reward you, Honorable Shaykh. This questioner says: Is it permissible to make du'a' in ruku' other than "O Allah, forgive me"?
Answer:
If he is praying alone, there is nothing wrong with it; he may prolong it as he wishes and increase his du'a'. However, if he is praying with a congregation, he should not burden them.
