Guys !!!
I have got a serious problem regarding this matter.First of all , I would request that you people explain your point of view in perspective of Quran , Sunnah and Athar-is-salaf-was-sualiheen regarding the issue that whether it is permissible or not to call upon the Beloved one pbuh for help in the time of distress and tribulations.
JazakAllah.

have u made up ur mind regarding this matter?

if so, perhaps u can share your thoughts and reasons.

Well surly we can cal any time of need to muhammad (pbuh) by sending him Darood. we should follow quran and sunnah first and the aslaaf so that we can guid better to ourselves. ishaAllah and when asking for help to Allah in term of Dua , add darood in the start and end of Dua , it will work inshaAllah.
