Hadith 30:14
Salih, the garment-seller, reported that his grandmother said, "I saw 'Ali, may Allah be pleased with him, buy fates for a dirham and put them in his blanket. I said to him (or a man said to him), 'I will carry it for you, Amir al-Mu'minin.' He said, 'No, the father of the family is the one who is the most entitled to carry it.'"
حَدَّثَنَا مُوسَى بْنُ بَحْرٍ، قَالَ: حَدَّثَنَا عَلِيُّ بْنُ هَاشِمِ بْنِ الْبَرِيدِ، قَالَ: حَدَّثَنَا صَالِحٌ بَيَّاعُ الأَكْسِيَةِ، عَنْ جَدَّتِهِ قَالَتْ: رَأَيْتُ عَلِيًّا رَضِيَ اللَّهُ عَنْهُ اشْتَرَى تَمْرًا بِدِرْهَمٍ، فَحَمَلَهُ فِي مِلْحَفَتِهِ، فَقُلْتُ لَهُ، أَوْ قَالَ لَهُ رَجُلٌ: أَحْمِلُ عَنْكَ يَا أَمِيرَ الْمُؤْمِنِينَ؟ قَالَ: لاَ، أَبُو الْعِيَالِ أَحَقُّ أَنْ يَحْمِلَ
