Salah behind certain Imams and how to approach them

forgive me, i was under the impression that even if salah behind a biddati is disliked, it is still better than praying salah without jamat.

Background:

قَالَ وَكَانَتْ لِي جَارِيَةٌ تَرْعَى غَنَمًا لِي قِبَلَ أُحُدٍ وَالْجَوَّانِيَّةِ فَاطَّلَعْتُ ذَاتَ يَوْمٍ فَإِذَا الذِّيبُ قَدْ ذَهَبَ بِشَاةٍ مِنْ غَنَمِهَا وَأَنَا رَجُلٌ مِنْ بَنِي آدَمَ آسَفُ كَمَا يَأْسَفُونَ لَكِنِّي صَكَكْتُهَا صَكَّةً فَأَتَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فَعَظَّمَ ذَلِكَ عَلَىَّ قُلْتُ يَا رَسُولَ اللَّهِ أَفَلاَ أُعْتِقُهَا قَالَ ‏"‏ ائْتِنِي بِهَا ‏"‏ ‏.‏ فَأَتَيْتُهُ بِهَا فَقَالَ لَهَا ‏"‏ أَيْنَ اللَّهُ ‏"‏ ‏.‏ قَالَتْ فِي السَّمَاءِ ‏.‏ قَالَ ‏"‏ مَنْ أَنَا ‏"‏ ‏.‏ قَالَتْ أَنْتَ رَسُولُ اللَّهِ ‏.‏ قَالَ ‏"‏ أَعْتِقْهَا فَإِنَّهَا مُؤْمِنَةٌ ‏"‏

 

One day I happened to pass that way and found that a wolf had carried a goat from her flock. I am after all a man from the posterity of Adam. I felt sorry as they (human beings) feel sorry. So I slapped her. I came to the Messenger of Allah (ﷺ) and felt (this act of mine) as something grievous I said: Messenger of Allah, should I not grant her freedom? He (the Holy Prophet) said: Bring her to me. So I brought her to him. He said to her: Where is Allah? She said: He is in the heaven. He said: Who am I? She said: Thou art the Messenger of Allah. He said: Grant her freedom, she is a believing woman. [Muslim]
 

Commentary:

Shaykh (Maulana) Suleiman Nadwi (RA) [1885-1953] the Khaleefa of Shaykh (Maulana) Ashraf Ali Thanwi (RA) [1863-1943] writes on page 43:

Allahu-Akbar! How many veils have covered the reality of Islam? Nabi (Sallaho Alaihe Wassallam) considered it sufficient for a person to raise a finger to testify (and attest to) their Islam while we don’t even consider someone a believer until he testifies and attests to all (elaborate) points (bullet point by bullet point) individually as contained in the Aqaid compilation of Imam Nasafi (RA) [1310]!

A Shaykhul-Hadeeth from Gujranwala (Pakistan) who has now passed away told me in my Youth:

Sectarianism in Pakistan has gone wild in Pakistan! Imagine if on the day of judgement Ulama from each sect would be given the authority to judge (Aqeedah) nobody would get in because there is NO AGREED upon group who is (perfect) Muslim according to Ulama even within Deobandees you have groups which label each other deviants so all praise be to my Allah (SWT) who is most Merciful of those who show Mercy.

I contacted Shaykh (Maulana) Marghoob Ahmed (HA) in UK about Fatwaas of Majlis about Shaykh (Maulana) Tariq Jameel (HA) and others so Maulana replied,

“Nobody becomes a Kaafir or deviant by random Fatwaas!”
