1426. hadíth
وَ سَأَلَ سَمَاعَةُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: عَنْ بَيْعِ اَلْحَيَوَانِ اِثْنَيْنِ بِوَاحِدٍ - فَقَالَ "إِذَا سَمَّيْتَ اَلسِّنَّ فَلاَ بَأْسَ".
Sama'ah asked Abu Abdullah (a.s) about selling two animals for one. Imam (a.s) said: "If you specify their age, then there is no harm."
