Mufti Mohammad Shafi’ (may Allah have mercy on him) said explaining the verses of sura al-Hujjarat,
‘Some scholars say that if someone has made a pious person his spiritual guide (murshid), and then he behaves rudely and with contempt towards him, similarly (to the effects of rude behavior towards the Prophet صلی اللہ علیہ وسلم described in these verses) this often becomes a source of removal of facility (tawfeeq) of good actions and leads to great deprivation. It eventually results in loss of wealth of faith (eman).
May Allah save us all from this. Ameen!”
