وَعَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ قَالَ: مَا كُنَّا نُبْعِدُ أَنَّ السَّكِينَةَ تَنْطِقُ عَلَى لِسَانِ عمر. رَوَاهُ الْبَيْهَقِيّ فِي «دَلَائِل النُّبُوَّة»
Ali (may Allah be pleased with him) said: We do not consider it unlikely that comforting words would flow from the tongue of Umar (may Allah be pleased with him). Sahih, narrated by Al-Bayhaqi in Dala'il al-Nubuwwah.
