Hadith 6043
وَفِي رِوَايَةِ أَبِي دَاوُدَ عَنْ أَبِي ذَرٍّ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «إِنَّ اللَّهَ وَضَعَ الْحَقَّ عَلَى لِسَان عمر يَقُول بِهِ»
In Abu Dawud's version on the authority of Abu Dharr he said, "God has placed truth on `Umar's tongue and he speaks it." Ali said. We did not think it impossible that the Sakina[*] should speak with `Umar's tongue. Baihaqi transmitted it in Dala'il an nubuwa.
