Addendum to the benefits of the hadith: (None of you should pray in a single garment unless something of it is on his shoulder).

The Shaykh : So, among the benefits of this hadith is the permissibility of praying in a single garment, and that it is necessary to place something of it on his shoulder. Is this on the basis of recommendation, obligation, or a detailed ruling? Distinguishing between the obligatory and the voluntary. And among the benefits of this hadith is that it is not a condition that a person wears two garments in prayer, meaning a shirt and trousers, for example. And if he prays in a shirt, that suffices, because the shirt will have something of it on his shoulders. And the issue: if someone prays in an izar only, does his prayer suffice? The answer: If he does not find anything else, there is no doubt that it suffices. And if he does find something, some of the scholars say that his prayer is invalid, and these are the ones who say that covering the shoulder is obligatory. And some of them say that his prayer is valid, but he has fallen short in covering the awrah, and this is the correct view. And this happens often on the days of Hajj; you find a man occupied, for example, in cooking or something else, and he prays in his izar and his rida' that is present. So, according to the stronger opinion, his prayer is valid. And according to the opinion that conditions covering one shoulder or both shoulders, his prayer is invalid. For this reason, a person should not be negligent in this issue, despite the disagreement among the scholars. Yes.
