The man is known to us to (possess) knowledge and virtue, exalting the Sunnah and giving service to it, and aiding the Madhab of Ahlus Sunnah Wal Jamaa-ah in warning against bigoted partisanship and blind following, and his books are beneficial. However, he is just like others amongst the scholars, he is not infallible; he is correct (at times) and mistaken (at times) and we hope for him two rewards in what he is correct and one reward in what he is mistaken, as established from the Prophet (sallal-laahu-alayhi-wasallam) that he said:

“When a haakim (i.e. a judge or scholar who has reached the station in knowledge making him qualified to perform Ijtihaad) strives to make a ruling and is correct, he receives two rewards, and if he makes a wrong ruling he receives one reward.’
