(b) Al-Zuhri says: The saying of Sayyiduna Abu Hurayrah (may Allah be pleased with him) was mentioned to Sayyiduna Ibn Umar (may Allah be pleased with them both), and he said: May Allah Almighty have mercy on him; he was a man of farming. (c) It is narrated from Sa'id bin al-Musayyib (may Allah have mercy on him), from the hadith of Sayyiduna Abu Hurayrah (may Allah be pleased with him), and in it is: two qirats (of reward will be deducted).
