Hadith #7

7ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ عَبْدِ الله بْنِ الْمُغِيرَةِ عَنْ عَبْدِ الله بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) أَنَّهُ قَالَ فِي الرَّجُلِ يُخْرِجُ زَكَاتَهُ فَيَقْسِمُ بَعْضَهَا وَيُبْقِي بَعْضَهَا يَلْتَمِسُ بِهَا الْمَوْضِعَ فَيَكُونُ مِنْ أَوَّلِهِ إِلَى آخِرِهِ ثَلاَثَةُ أَشْهُرٍ قَالَ لاَ بَأْسَ.

7. Ali ibn Ibrahim has narrated from his father from ’Abd Allah ibn af-Mughirah from ’Abd Allah ibn Sinan who has said the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, about a man who pays his Zakat. He distributes a certain amount of it and keeps a certain amount to find proper recipient and this takes three months altogether. He (the Imam) said, ‘It is not harmful.’”
