1ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ بَاعَ أَبِي أَرْضاً مِنْ سُلَيْمَانَ بْنِ عَبْدِ الْمَلِكِ بِمَالٍ فَاشْتَرَطَ فِي بَيْعِهِ أَنْ يُزَكِّيَ هَذَا الْمَالَ مِنْ عِنْدِهِ لِسِتِّ سِنِينَ.

1. Ali ibn Ibrahim has narrated from his father from ibn abu ‘ Umayr from Hammad from al-Halabiy who has said the following: “Abu ’Abd Allah, ‘Alayhi al-Salam, has said, ‘My father purchased a piece of land from Sulayman ibn ‘Abd al-Malik for a certain amount with a condition that he (Sulayman) will pay its Zakat for six years.’”

2ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ مَحْبُوبٍ عَنْ عَبْدِ الله بْنِ سِنَانٍ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) يَقُولُ بَاعَ أَبِي مِنْ هِشَامِ بْنِ عَبْدِ الْمَلِكِ أَرْضاً لَهُ بِكَذَا وَكَذَا أَلْفَ دِينَارٍ وَاشْتَرَطَ عَلَيْهِ زَكَاةَ ذَلِكَ الْمَالِ عَشْرَ سِنِينَ وَإِنَّمَا فَعَلَ ذَلِكَ لأَنَّ هِشَاماً كَانَ هُوَ الْوَالِيَ.

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Hassan ibn Mahbub from ‘Abd Allah ibn Sinan who has said the following: “I once heard abu ‘Abd Allah, ‘Alayhi al-Salam, say, ‘My father purchased a piece of land from Hisham ibn ‘Abd al-Malik for such and such hundred thousand dinar with a condition that he will pay its Zakat for ten years. He did it as such because Hisham was the ruler.’”
