Abu Khuzaimah Ansari
You alleged the Ahlul Hadith and Salafis insult Imam Abu Hanifah. This is totally incorrect, our Madhab (the Madhab of Ahlul Hadith) does not permit using derogatory words for Imam Abu Hanifah. However, everyone has the right to critique Abu Hanifah’s ijtihad and raise objection against his Madhab.
(Imam Malik said) Everyone’s statement can be accepted or rejected except the statement of Allah’s Messenger Sallalahu Alayhi Wasallam. (Iqd ul-Jid (p.122), al-Insaf Fi Bayan Sabab al-Ikhtilaf (p.13), Muqaddimah Sifatus Salah (p.49)
Insults and abuse actually emanate for your house (ie the Hanafi Madhab) for example in your Madhab it is permissible to write the Quran with blood from a nosebleed, to write the Quran with urine, giving fiqh a greater status than the Quran, in fact giving women body parts an even greater status than both etc.
Furthermore, Durr al-Mukhtar Sharif mentions, the prayer behind an individual who swears at the Prophet Sallalahu Alayhi Wasallam is makruh tanzihi (prohibitively disliked) (Durr al-Mukhtar Ala Hamish ash-Shami (1/561)
To the extent that according to your fiqh such a person does not become a Kafir. (Durr al-Mukhtar (1/561)
You also believe if a person puts his feet on the Quran with the intention of desecrating it in a blasphemous manner, only then is he a Kafir otherwise he is not. (Fatawa Alamghiri (5/322)
Is not placing his feet in the Quran blasphemous and desecrating it by default?
They further say, the one who accuses all the mothers of the believers of fornication except A’ishah RadhiAllahu Anha is not a Kafir and much more.
