20. Abu Hurairah (radhiAllaahu' anhu) said that Rasoolullah (sallallahu 'alaihi

wasallam) said There is no wudoo for him who does not mention Allaah's name upon it. [Reported by Ibn Maajah (no.399), At-Tirmidhee (no.26), Abu Dawood (no.101) and others. Ash-Shaikh al-Albaani says: hadith sahih (sahih ul-Jaarni', no.7444)]. Imam Ahmad in one of his two sayings is of the opinion that it is obligatory in wudoo, ghusl, and Tayammum. He was followed in this opinion by Abu Bakr, and it is the saying of al-Hasan (al-Basaree) and Imam Ishaaq - as reported by Ibn Qudaamah in 'al-Mughnee' (1/84) and their proof is this hadith. Ibn Qudaamah adds: If we take the saying that it is obligatory, then the wudoo of one who deliberately leaves it is not correct as he has left an obligatory duty in Purification - just as if he had left the intention; and if he left it forgetfully then his purification is correct. (Al-Mughnee). And this is the saying that we regard as being correct. As for Ibn Taymiyyah (rahimahullah) he held it to be obligatory if the related hadith was authentic - as occurs in his Kitaab-ul-Imaan - and the hadith is authentic, so therefore his opinion (rahimahullah) is that it is obligatory.
