Hadith 17:901
Abu Bakr narrated to us, he said: Zayd ibn al-Hubab narrated to us, he said: Mu'awiyah ibn Salih narrated to us, he said: Yahya ibn Sa'id al-Kala'i narrated to me, from Jubayr ibn Nufayr al-Hadrami, that Umm al-Darda' sent him to Nawfal ibn so-and-so and Waqqas, who were with him, [as they were] telling stories in the mosque. She said: "Tell them both to fear Allah, and let their exhortation to the people be for their own selves."
حدثنا أبو بكر قال حدثنا زيد بن الحباب حدثنا معاوية بن صالح قال حدثني يحيى بن سعيد الكلاعي عن جبير بن نفير الحضرمي أن أم الدرداء بعثته إلى نوفل بن فلان وقاص معه يقصان في المسجد فقالت قل لهما ليتقيا الله وتكون موعظتهما للناس لأنفسهما
