Asalam Alaikum Brother,
First, the reason for presenting the video of Naṣīruddīn Naṣīr was because in the video of Pir Syed Muzaffar Shāh he said Pir Ṣaḥib was cutting the jarḥ (the foundations) how could he like the fruits that bear from it (i.e deobandis) whereas in the video of Naṣīruddīn Naṣīr he said about Pīr Mehr ʿAlī Shāh having Taʿaluq with the deobandis and even being taught by them. That was were the question of "whos word is weightier popped up from" one who is from Pir Ṣaḥibs direct lineage or Syed Muzaffar Shāh this is where the thread had become sidetracked unfortunately
Second why would ʿAllāmah Aṭā' Muḥammad write this in his book if he didnt believe it to be authentic. The reason I bring up this issue of silence is because we see it get used against us. Especially by the likes of Tahir ul and the deobandi's. The point was how do we answer this and why did Aṭā' muhamamd bandyalvi write this.
Akhi you totally missing the point. Is there any proof that somebody presented Ḥusām al-Haramayn to Pir Sahib and then Pir sahib did not takfir them.
There are two side to this, one where Atā Muhammad bandyalvi and Naṣīruddīn Naṣīr claim Pir sahib did not takfir them and another side which says He did takfir them when fatwa is presented to him and also his eldest son spoke in favour of later.
Here one side doesnt mention about fatwa being presented to Pir saheb while other side say when its presented he did takfir them. This does makes sense considering how Pir sahib criticized the Ismail dehlvi's book. There is no conclusive proof about whether Pir saheb really takfir them or he remained silent. All we have is secondary sources.
We say to deobandis to bring a conclusive proof which shows Pir sahib did not takfir them even after learning about the fatwa or else shut your mouth. You wanna only accept those statements which favour your argument. This is just one being intellectually dishonest.
I personally think we shouldn't waste our energy and time on these kind of trivial issues, Thats why brother Aqdas reply and Muzzafar Shah saheb's video is more than enough to clarifying the issue. As Al-Shafi’i, may Allah have mercy on him, said, “Among the degradation of knowledge is that you debate everyone who debates you, or you argue with everyone who argues with you.”
