The Shaykh, Ubayd ibn 'Abdillaah Al-Jaabiree, was asked today about those who say that when a person claims salafiyyah for himself that he must say "in shaa' Allaah" like he says it when he calls himself a believer...
The shaykh replied that, no, there is no need for this, except for someone who fears that he is purifying himself, then he MAY say it, without it being waajib on him.
Furthermore, he was asked about those who prohibit ascribing to Salafiyyah except that they say "in shaa' Allaah", since it is a kind of self tazkiyah.
The Shaykh said, "So the Tableeghees and the Ikhwaanees can ascribe themselves (to Tableeghiyyah and Ikhwaaniyyah), but the Salafee may not do so since it is a self tazkiyah!?" He then re-affirmed the correct position that people are not to be blamed for their ascription to Salafiyyah as Shaykh Al-Islaam Ibn Taymiyyah mentioned so many centuries ago.
(Shaykhul-Islaam Ibn Taymiyyah said:"There is no blame upon the one who makes apparent the madthab (way) of the Salaf and affiliates himself with it and attaches himself to it. Rather it is obligatory to accept that from him by agreement, for verily the madthab of the Salaf is nothing but the truth." -Majmoo‘ul-Fataawaa (4/149) of Ibn Taymiyyah)
