Shaikh Ahmad Baazmool (hafithahullah) said,
A person's actions must also give Tazkiyyah for its owner due to them being in conformity to the Sunnah. If a man is in contradiction to the principles of Salafiyyah, him having a Tazkiyyah from a Scholar will NOT avail him. Rather, if he shows the Scholars one face and then goes and acts in a manner that is contrary to the Da'wah (As-Salafiyyah), his Tazkiyyah would in fact strengthen the Jarh against him because it would have proven his treachery and that he is a person who plays games.
Translator’s note: The Shaikh (hafithahullah) made this statement while urging us to be humble upright Salafis on the path and cautioning, that no one should ever let anyone’s praise for them deceive them into believing that they are invulnerable to error or from going astray. Look at how people were praised and had Tazkiyaat from the Ulama but none of that availed them due to their opposition to the Sunnah. Reflect on the likes of Fawzee Al Bahrainee, ‘Abdul ‘Atheem Al Badawee, Yahyaa Al Haajooree, Faalih Al Harbee, Mustapha Al ‘Adawee and other than them. Those who at a time, were praised by the Scholars and Imaams due to them displaying a face which complied with Salafiyyah, only to be later exposed for their other faces which are in stark contrast to Salafiyyah.
