Question: What is your opinion regarding the book “Fiqh as-Sunnah” of Sayyid Saabiq?
Response: No doubt it is from amongst the good books, because of the many issues it mentions with evidence. However, it is not free from errors; And as Ibn Rajab (rahima-hullaah) said in the introduction to the book, “al-Qawaa.id al-Fiqhiyyah”:
‘Allaah has refused to protect any book [from errors] other than His Book, however, the one who is fair is the one who overlooks the few mistakes of a man for the majority of his correctness.’
So, there is no doubt that this book is beneficial. However, I do not advise anyone to refer to it except a student of knowledge who is able to differentiate between that which is authentic and that which is weak, as there are many weak issues [in the book].
From amongst these is the opinion that Salaatut-Tasbeeh is mustahab (recommended). However, Shaykh al-Islaam Ibn Taymiyyah (rahima-hullaah) says regarding it, that it’s hadeeth is a forgery. And he said, indeed none of the Imaams declared it to be mustahab and when Imaam Ahmad was asked about it, he brushed his hand [as if to remove dust] as if to imply his detesting this.
