Al-Kāfi|Volume 3|Book 5|Chapter 12
2ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ رَفَعَهُ عَنْ أَبِي بَصِيرٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ قُلْتُ لَهُ هَلْ لِلزَّكَاةِ وَقْتٌ مَعْلُومٌ تُعْطَى فِيهِ فَقَالَ إِنَّ ذَلِكَ لَيَخْتَلِفُ فِي إِصَابَةِ الرَّجُلِ الْمَالَ وَأَمَّا الْفِطْرَةُ فَإِنَّهَا مَعْلُومَةٌ.
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad in a marfu‘ manner from abu Basir who has said the following: “I once asked abu ‘Abd Allah عليه السلام, Is there a definite time to pay Zakat? He (the Imam) said, ‘That depends on one’s earnings. However, the time for al-Fitrah is definite.”’
