٤ـ حُمَيْدُ بْنُ زِيَادٍ عَنِ ابْنِ سَمَاعَةَ عَنْ غَيْرِ وَاحِدٍ عَنْ أَبَانٍ عَنْ زَيْدٍ الشَّحَّامِ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) أَخْرُجُ مِنَ الْمَسْجِدِ وَفِي ثَوْبِي حَصَاةٌ قَالَ فَرُدَّهَا أَوِ اطْرَحْهَا فِي مَسْجِدٍ. 
4. Humayd ibn Ziyad has narrated from ibn Sama‘ah and from more than one person from Aban from Zayd al-Shahham who has said the following: “I once asked abu ‘Abd Allah , about the pebbles that I find with me after coming out of the Masjid. He (the Imam) said, ‘Return them or throw in the Masjid.’”
