Hadith 14:18
Narrated Zaid bin Khaled al-Juhani (RA):
The Prophet (ﷺ) said: "Shall I not inform you who is the best witness? He is the one who produces his testimony before he is asked for it." [Reported by Muslim].
عَنْ زَيْدِ بْنِ خَالِدٍ اَلْجُهَنِيِّ - رضى الله عنه - أَنَّ اَلنَّبِيَّ - صلى الله عليه وسلم -قَالَ: { "أَلَا أُخْبِرُكُمْ بِخَيْرِ اَلشُّهَدَاءِ? اَلَّذِي يَأْتِي بِشَهَادَتِهِ قَبْلَ أَنْ يُسْأَلَهَا" } رَوَاهُ مُسْلِم ٌ
