The evil Nasibi mulla, Mahmood Ahmad Abbasi, had the audacity to criticize our beloved Mawla Ali (Karam Allahu wajhahu) in his stupid book Khilafat Mu'awiya o Yazid.
The Prophet (Sallallahu alaihi wasallam) said about Ali (Radiyallahu anhu):
إِنَّ عَلِيًّا مِنِّي وَأَنَا مِنْهُ , وَهُوَ وَلِيُّ كُلِّ مُؤْمِنٍ بَعْدِي
Translation: “Verily, Ali is from me and I am from him, and he is the Guardian of every believer after me.” (Tirmidhi)
But the spiritually blind mulla Mahmood Ahmad Abbasi wrote that it was unfortunate that Ali (radiyallahu anhu) became the fourth Khalifah of the Muslim ummah:
مگر افسوس حضرت موصوف نے اپنے بھائی کا مشورہ قبول نہ فرمایا اور بیعت لے لی۔
Translation: “It is very unfortunate that Hadrat Ali did not accept the advice of his brother and took the Bai'at (pledge of allegiance to become Khalifah)”
