the famous incident in Rawalpindi, narrated as follows:
It is narrated in Dharb-i-Shamshir that once in Salar Gah, Rawalpindi, an argument started between Molwi Bahadarudin [imam of local masjid] and Muhammad Ashraf Khan regarding the takfir of Ulama of Deoband. This argument led to a debate and both sides gathered on the fixed date for the debate. Right before the debate, elders of the town suggested that instead of debating both sides should accept Pir Mahr Ali Shah as the judge. Both sides agreed to this and went to Pir Mahr Ali Shah and presented the situation as follow,
Ashraf Khan says that if any imam of masjid doesn't consider these five individuals:
1.Mawlana Shah Ismail Shahid
2.Mawlana Qasim Nanotwi
3.Mawlana Rashid Ahmad Gangohi
4.Mawlana Khalil Ahmad Saharanpuri
5.Mawlana Ashraf Ali Thanwi
to be kafir, salah is not valid behind him.
Pir Mahr Ali Shah was angered by this statement and said:
"If these five mashaikh are not Muslim then there is no Muslim in the World and whoever does their takfir, salah is not valid behind him."
This was also written by Mufti Qari Ghulam Muhammad of Golra Sharif."
