Qurʾān Bukhārī Muslim Nasāʾī Abū Dāwūd Tirmidhī Ibn Mājah Mālik Aḥmad Dārimī Ḥākim Ibn Ḥibbān Ṭabarānī Nasāʾī's Kubrá Bayhaqī al-Luʾluʾ wa-al-Marjān Ibn Rajab's Fifty Riyāḍ al-Ṣāliḥīn Aḥmad's Zuhd Suyūṭī
nasai:2510 – Qutaybah > Ḥammād > Ayyūb > Abū Rajāʾ > Ibn ʿAbbās Yakhṭub > Minbarikum / Minbar al-Baṣrah > Ṣadaqah al-Fiṭr Ṣāʿ from Ṭaʿām

I heard Ibn 'Abbas deliver a Khutbah from your Minbar - meaning the Minbar in Al-Basrah - saying: 'Sadaqatul Fitr is a Sa' of food." (Sahih) Abu 'Abdur-Rahman (An-Nasa'i) said: This is the most reliable of the three.  

النسائي:٢٥١٠ – أَخْبَرَنَا قُتَيْبَةُ قَالَ حَدَّثَنَا حَمَّادٌ عَنْ أَيُّوبَ عَنْ أَبِي رَجَاءٍ قَالَ سَمِعْتُ ابْنَ عَبَّاسٍ يَخْطُبُ عَلَى مِنْبَرِكُمْ يَعْنِي مِنْبَرَ الْبَصْرَةِ يَقُولُ صَدَقَةُ الْفِطْرِ صَاعٌ مِنْ طَعَامٍ قَالَ

أَبُو عَبْدِ الرَّحْمَنِ هَذَا أَثْبَتُ الثَّلاَثَةِ

the Messenger of Allah cut off (a thief's hand) for a shield. (Sahih) Abu 'Abdur-Rahman (An-Nasai) said: This is a mistake. (Using translation from Nasāʾī 4911)   

الكبرى للنسائي:٢٦٠٥ – أَخْبَرَنَا مُحَمَّدُ بْنُ أَبَانَ قَالَ أَخْبَرَنَا مَعْنٌ عَنِ ابْنِ أَبِي ذِئْبٍ عَنِ الزُّهْرِيِّ عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ قَالَ يُقَالُ §الصِّيَامُ فِي السَّفَرِ كَالْإِفْطَارِ فِي الْحَضَرِ قَالَ

أَبُو عَبْدِ الرَّحْمَنِ هَذَا خَطَأٌ
