Question: Why does the pilgrim wear those clothes during Hajj?
Response: All praise be to Allāh.
Allāh commanded us, on the tongue of his Messenger Muḥammad ﷺ to wear the izār (lower garment) and ridā (upper garment) during Ḥajj and ‘Umrah for some wisdom that is known to him.
So we must obey (him) to hope to earn the reward, whether we know the wisdom or not. Some of what the scholars have said concerning that is that it is a reminder on how the people will be on the Day of Gathering and Raising, the Day of Resurrection, to make the pilgrim feel humble and that rich and poor are equal.
We ask Allāh to give us and you success, make us correct and to remain steadfast in adhering to the truth until we meet him.
And with Allāh lies All the success, and may he send praise and peace upon our Prophet Muḥammad, his family and his companions.

لسؤال: لماذا الحاج يرتدي تلك الملابس في الحج؟ ا
لإجابة: أمر الله على لسان رسوله محمد ﷺ بارتداء الإزار والرداء في الحج وفي العمرة لحكمة يعلمها، فوجب علينا الامتثال؛ رجاءَ الثواب، سواء علمنا الحكمة أم لم نعلمها.
ومما ذكره العلماء في ذلك: التذكير بحال الناس يوم الجمع والنشور يوم القيامة، وإشعار الحاج بالتواضع والتساوي بين الغني والفقير.
وبالله التوفيق وصلى الله على نبينا محمد وآله وصحبه وسلم .
