A beggar came and asked Ibn Abbas for help.Ibn Abbas asked him, "Do you bear witness that there is no god but Allah?"The man replied, "Yes."Ibn Abbas asked, "Do you bear witness that Muhammad is the Messenger of Allah?"The man replied, "Yes."Ibn Abbas asked, "Do you fast during Ramadan?"The man replied, "Yes."Ibn Abbas said, "You have asked, and the one who asks has a right. It is our duty to give to you."He then gave him a garment and said, "I heard the Messenger of Allah ﷺ say, 'No Muslim clothes another Muslim with a garment except that he remains under Allah's protection as long as a single shred of it remains on him.'"
جاء سائل فسأل ابن عباس، فقال ابن عباس للسائل: أتشهد أن لا إله إلا الله؟ قال: نعم، قال: أتشهد أن محمدا رسول الله؟ قال: نعم، قال: وتصوم رمضان؟ قال: نعم، قال: سألت، وللسائل حق، إنه لحق علينا أن نصلك، فأعطاه ثوبا، ثم قال: سمعت رسول الله ﷺ يقول: ما من مسلم كسا مسلما ثوبا، إلا كان في حفظ من الله، ما دام منه عليه خرقة.
Tirmidhi (2484) narrated it, and the wording here is his, as did Bukhari in Tarikh al-Kabir (9/3), and Hakim (4/196), all of them through various routes from Khalid bin Tahman Abu Ala Khaffaf, from Husayn bin Malik, who said, then he related it.Hakim said, "This is a hadith sahih in isnad, and the two of them [Bukhari and Muslim] did not narrate it." Dhahabi followed up on this by saying, Khalid is daif.I say, Ibn Main declared him daif, but Abu Hatim said, "His standing is one of truthfulness." Ibn Hibban mentioned him among the trustworthy narrators. Ibn Adi said, "I have not seen in the amount he narrates any munkar hadith." So his hadith is hasan as long as there is no shudhudh or nakarah in it. The isnad is therefore hasan, and Tirmidhi also graded it hasan.There was disagreement over whether it is raised to the Prophet (marfu) or stopped at the companion (mawquf). Abu Hatim was asked about it and said, "People raise it to the Prophet, and in my view the raised version is sahih." Ilal of Ibn Abu Hatim (1995).
