It is established from the Prophet (peace and blessings be upon him) that when he performed the full ritual bath, he did not perform the ablution. Is it permissible for a Muslim to suffice with the intention regarding the ablution, or is the ablution obligatory before the full ritual bath?

Al-Halabi : In the authentic hadith, it is stated that the Prophet (peace and blessings be upon him), when he performed the full ritual bath, did not perform the ablution. Is it sufficient to suffice with the intention regarding the ablution? Or is the ablution obligatory before the full ritual bath, as is authentic from him (peace and blessings be upon him) in his practical Sunnah?

The Shaykh : There is no doubt that combining the full ritual bath with the ablution before it is the Sunnah, without doubt or hesitation. However, the point of disagreement is whether this ablution before the full ritual bath is obligatory? Such that if one performs the full ritual bath and does not perform the ablution, his prayer is not valid? Or is it not obligatory, but rather a Sunnah? This is what we choose: that the ablution before the full ritual bath is a Sunnah, and not an obligatory matter, based on the hadith he referred to.The questioner .
