Hadith 1363B3

قَالَ مَالِك : وَتَفْسِيرُ مَا كُرِهَ مِنْ ذَلِكَ : أَنْ يُؤْخَذَ الْبَعِيرُ بِالْبَعِيرَيْنِ لَيْسَ بَيْنَهُمَا تَفَاضُلٌ فِي نَجَابَةٍ وَلَا رِحْلَةٍ، فَإِذَا كَانَ هَذَا عَلَى مَا وَصَفْتُ لَكَ فَلَا يُشْتَرَى مِنْهُ اثْنَانِ بِوَاحِدٍ إِلَى أَجَلٍ، وَلَا بَأْسَ أَنْ تَبِيعَ مَا اشْتَرَيْتَ مِنْهَا قَبْلَ أَنْ تَسْتَوْفِيَهُ مِنْ غَيْرِ الَّذِي اشْتَرَيْتَهُ مِنْهُ إِذَا انْتَقَدْتَ ثَمَنَهُ .
Imam Malik, may Allah have mercy on him, said that its example is like those camels which are alike, having no difference among them in essence and in bearing loads. So, among such camels, to give two camels and take one camel in return on a promise is not permissible. However, there is no objection if a camel is bought and, before taking possession, it is sold to another person, provided its price is taken in cash.
