"I undertook a financial responsibility. [1] Then I came to the Prophet and asked him (for help) concerning that. He said: 'Asking (for money) is not permissible except for three: A man who undertakes a financial responsibility between people; he may ask for help with that until the matter is settled, then he should refrain (from asking)."' (Using translation from Nasāʾī 2579)
تَحَمَّلْتُ حَمَالَةً فَأَتَيْتُ النَّبِيَّ ﷺ فَسَأَلْتُهُ فِيهَا قَالَ إِنَّ الْمَسْأَلَةَ لَا تَحِلُّ إِلَّا لِثَلَاثَةٍ رَجُلٍ تَحَمَّلَ بِحَمَالَةٍ بَيْنَ قَوْمٍ فَيَسَأَلُ فِيهَا حَتَّى يُؤَدِّيَهَا ثُمَّ يُمْسِكَ
