A spiritual aspirant missed writing bismillah (In the name of Allah) at the beginning of his islahi letter.
Sayyidi wa sanadi Mufti Mohammad Taqi Usmani (Allah preserve him) corrected him,
‘Write Bismillah at the beginning of the letter or 786 (when without wudhu) and recite bismillah.’
* bismillah is a verse of Holy Quran. It must not be touched without being in state of wudhu
