Musannaf Ibn Abi Shaybah
كتاب صلاة التطوع والإمامةBook of Voluntary Prayers and Imamate
من كان لا يتطوع في المسجدThose who did not pray nafl in the mosque
Hadith 6517
٦٥١٧ - حدثنا وكيع قال: (حدثنا) (١) الأعمش عن إبراهيم قال: سئل حذيفة عن التطوع في المسجد يعني بعد الفريضة فقال: إني لأكرهه بينما هم جميعًا في الصلاة (إذ) (٢) اختلفوا (٣).
Ibrahim reports that Hazrat Hudhaifa (may Allah be pleased with him) was asked about performing voluntary prayers in the mosque after the obligatory prayer, so he replied that he considered it disliked. This is because everyone is performing prayers there, and in this way, there will be differences in their prayers!
