Sayyidi wa sanadi Mufti Mohammad Taqi Usmani (Allah preserve him) mentioned the difference of opinions amongst the scholars (fuqaha) regarding the Prophetic sayings (hadith) that to what extent the hands must be raised while starting the salah. He continued,
‘However, all of them agree that the palms should be facing the qibla direction.
Many knowledgeable individuals and students (of religious institutes) falter in this practice.’
