In The Name of Allah, The Most Merciful, The Bestower of Mercy.

The Messenger (peace and blessings of Allah be upon him) said, “Verily, Allah blocks the repentance of every adherent to Bidah until he abandons his bidah”. [1]

Imaam Al-Albaani (may Allah have mercy upon him) said: “This does not constitute a Shariah ruling (i.e. does not mean that the Shariah prevents the person from repentance as a rule), but the meaning of the hadith is that an individual following the path of Bidah and it is made fairseeming to him that it is good, this one does not repent from it. This is the barrier that hinders and prevents the adherent of Bidah from seeking repentance. (i.e. to abandon the Bidah) In this subject matter here, the scholars said that Bidah in the religion is more perilous than sin, as I explained to you”. [2]

So, let it be known to Muhammad Hijaab and all those who speak ill of the erudite Salafi Scholar Al-Allaamah Saalih Al-Fawzaan or any other upright scholar, that his wrongful actions can be summed up in the following poem:

يُخاطِبُني السَفيهُ بِكُلِّ قُبحٍ
فَأَكرَهُ أَن أَكونَ لَهُ مُجيبا
يَزيدُ سَفاهَةً فَأَزيدُ حِلماً
كَعودٍ زادَهُ الإِحراقُ طيبا

The fool addresses me with every repugnant (expression etc), but I hate to be a respondent, so he increases in foolishness and I increase in forbearance, just as Oud increases in good smell when burnt.
