Is it obligatory to preserve the prophetic supplications as they were reported, or is it permissible to exercise ijtihad by replacing words with their synonyms? What is the difference between "Allahumma unsour li" (O Allah, grant victory for me) and "Allahumma unsurni" (O Allah, grant me victory)? What is the meaning of "wamkur li wala tamkur alayya" (and scheme for me and do not scheme against me)? And what is the meaning of scheming attributed to Allah the Almighty?

Prophetic supplications (Duas) must be preserved verbatim in a special place and not altered. The phrase "وانصر لي" (and grant me victory) was not mentioned in the Hadith or the Arabic language. The correct phrasing is "وانصرني ولا تنصر علي" (and grant me victory and do not grant victory over me), and its meaning is: Make me victorious over the disbelievers, or grant me victory over my soul that inclines to evil. The meaning of "امكر لي ولا تمكر علي" (devise for me and do not devise against me) is: Guide me to a way of repelling my enemies, and do not guide my enemy to a way of repelling me from himself. And plotting (al-makr) from Allah is the infliction of His punishment upon His enemies without their knowledge, or the gradual enticement of a servant through obedience which then becomes rejected. It is not permissible to describe Allah with plotting (al-makr) except by way of similitude, as in His Almighty saying: "And they plot, and Allah plots. And Allah is the best of plotters." (Quran 8:30).
