Mishkat al-Masabih 9 Supplications كتاب الدعوات 33

وَعَنْ أُبَيِّ بْنِ كَعْبٍ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا ذَكَرَ أَحَدًا فَدَعَا لَهُ بَدَأَ بِنَفْسِهِ رَوَاهُ التِّرْمِذِيُّ وَقَالَ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ صَحِيح

Ubayy b. Ka‘b said that when God’s messenger mentioned anyone for whom he made supplication, he began with himself. Tirmidhi transmitted it, saying this is a hasan gharib sahih tradition.
