وَعَنْ أُسَامَةَ بْنِ زَيْدٍ قَالَ: لَمَّا ثَقُلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ هَبَطْتُ وَهَبَطَ النَّاسُ الْمَدِينَةَ فَدَخَلْتُ عَلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَقَدْ أُصْمِتَ فَلَمْ يَتَكَلَّمْ فَجَعَلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَضَعُ عَليّ يَدَيْهِ وَيَرْفَعُهُمَا فَأَعْرِفُ أَنَّهُ يَدْعُو لِي. رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ غَرِيبٌ

Usama b. Zaid said: When God’s messenger became very weak[*] the people and I came down to Medina. I went in to visit God’s apostle who was tongue-tied and unable to speak: but he was placing his hands on me and raising them, and I recognised that he was invoking a blessing on me. *i.e., during his last illness. Tirmidhi transmitted it, saying this is a gharib tradition.
