عَنْ حُذَيْفَةَ بْنِ أَسِيدٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ جَاءَ ذَاتَ يَوْمٍ، فَقَالَ: ((صَلُّوا عَلَى أَخٍ لَكُمْ مَاتَ بِغَيْرِ أَرْضِكُمْ))، قَالُوا: مَنْ هُوَ يَا رَسُولَ اللَّهِ! قَالَ: ((صَحْمَةُ النَّجَاشِيُّ))، فَقَامُوا فَصَلَّوْا عَلَيْهِ
It is narrated from Sayyiduna Hudhaifah bin Asid (may Allah be pleased with him) that one day the Messenger of Allah (peace and blessings be upon him) came and said: "Offer the funeral prayer for your brother who has passed away in a foreign land." The companions asked: "O Messenger of Allah! Who is he?" He replied: "Sahmah Najashi." Thus, the companions stood up and offered his funeral prayer.
