Is it true that the first hukum among all the ahkaam of Islam ordered to do as a fard on the Muslim ummah at the time of the Prophet (SAWS) is salaat (namaaz). Is it true that the Prophet (SAWS) used to do rafaa yadain (raising both hands in salaat) in Mecca because the kuffar used to hide idols in their armpits and under their arms and this way when kuffar did rafaa yadain all the idols used to fall down. (3) It says somewhere in Taaleem-ul-islam that it is makrooh for women to wrap their hair and tie them on their head during salaat, could you please explain what it means.
It is undesirable for women to tie their hair and make a bundle of it whether in the prayer or outside of the prayer.
