Someone asked, "Messenger of Allah, how will you recognize those of your community whom you have never seen?"He replied, "They will have radiant faces and bright limbs from the marks of ablution."
قيل يا رسول الله كيف تعرف من لم تر من أمتك؟ قال: غر محجلون بلق من آثار الوضوء.
Ibn Majah reported it (284), Muhammad bin Yahya Nisaburi told us, he said, Abu Walid Hisham bin Abdul-Malik told us, he said, Hammad told us, from Asim, from Zirr bin Hubaysh, that Abdullah bin Masud said... [as previously mentioned]. Its isnad is hasan due to discussion regarding Asim, who is Ibn Abu Najud. Busiri likewise graded it hasan in Zawaid Ibn Majah. Ibn Hibban also reported it in his Sahih (1047) through the route of Hammad, that is Ibn Salama, with a similar isnad.On this subject there is also a report from Abu Umama, who said that the Messenger of Allah ﷺ said, "There is no one from my nation whom I do not recognize on the Day of Resurrection." They said, "Messenger of Allah, how do you recognize those you have seen and those you have not seen?" He said, "Those I have seen and those I have not seen, by their radiance and brightness from the traces of purification." Imam Ahmad reported it (22257) and Tabarani in Kabir (7509), both from Abdul-Rahman bin Mahdi, from Muawiya bin Salih, from Abu Utba Kindi, from Abu Umama, who related the same. Abu Utba Kindi had no one narrate from him except Muawiya bin Salih, and no one deemed him reliable, though Ibn Hibban mentioned him in Thiqat (5/570).There is also a report from Jabir, who said, it was asked, "Messenger of Allah, how do you recognize those of your nation you have not seen?" He said, "By their radiance, I think he said, brightness from the traces of wudu." Bazzar reported it, in Kashf Astar (254), and it contains Yahya bin Yaman Ajli Kufi, whom Yahya bin Main and Nasai declared daif. Ibn Adi said, "Most of what he narrates is not preserved, and he himself does not deliberately lie, but he errs and becomes confused." Kamil (7/2691). Ibn Hibban did not mention him among his reliable narrators despite his leniency. Nevertheless, Hafiz Haythami said in Majma (1/225), "Its isnad is hasan." Perhaps he said this because of the abundance of its corroborating reports.As for the word in the hadith, "balaq," it comes from the horse being described as "balaq," having a mixture of black and white.
