Hadhrat Shaykh Ul Islam writes after describing the signs and the Wahhabi ordeal in the light of the Hadith:
Translation: It can’t be doubted that this faction is suffering from some deep-seated deprivation because of which the True Prophet (Sallallahu alaihi wa sallam) said that they will never return to the religion; but one reason which seems obvious is that in their zeal for defending Tauheed, eliminating shirk and Bida’a (innovations), they not only disrespect the beloved of Almighty Allah, but also learn it and teach it to others as if they are teaching the principles of Deen, which Allah’s sense of honor cannot bear and it destroys them. (Anwaar-e-Ahmadi, 324, 325)
Shaykh Ul Islam instructs the Wahhabis to give up disrespect and to follow the manners of the Companions
Translation: The Wahhabis should fear Almighty Allah that they see the grandeur and superiority of the Holy Prophet (Sallallahu alaihi wa sallam) in the Holy Quran and the Hadith, they hear it from the Muslims but ignore them and search for such Hadith, which outwardly diminish the superiority of the Holy Prophet (Sallallahu alaihi wa sallam). Will such Salaat, such fasts and such belief in the Holy Prophet (Sallallahu alaihi wa sallam) be of any benefit? We have an example of a large group of people that these things will not benefit; so we give them well-meaning advice to leave this way and adopt the manners of the Companions.
