The Prophet ﷺ forbade the type of sale which involves risk (or uncertainty) and a transaction determined by throwing stones.  

أَنَّ النَّبِيَّ ﷺ نَهَى عَنْ بَيْعِ الْغَرَرِ زَادَ عُثْمَانُ وَالْحَصَاةِ  

The Prophet ﷺ forbade two types of business transactions and two ways of dressing. The two types of business transactions are mulamasah and munabadhah. As regards the two ways of dressing, they are the wrapping of the samma', and that when a man wraps himself up in a single garment while sitting in such a way that he does not cover his private parts or there is no garment on his private parts.  

أَنَّ النَّبِيَّ ﷺ نَهَى عَنْ بَيْعَتَيْنِ وَعَنْ لِبْسَتَيْنِ أَمَّا الْبَيْعَتَانِ فَالْمُلاَمَسَةُ وَالْمُنَابَذَةُ وَأَمَّا اللِّبْسَتَانِ فَاشْتِمَالُ الصَّمَّاءِ وَأَنْ يَحْتَبِيَ الرَّجُلُ فِي ثَوْبٍ وَاحِدٍ كَاشِفًا عَنْ فَرْجِهِ أَوْ لَيْسَ عَلَى فَرْجِهِ مِنْهُ شَىْءٌ  

"Wearing the samma' means that a man puts his garment over his left shoulder and keeps his right side uncovered. Munabadhah means that a man says (to another): If I throw this garment to you, the sale will be certain. Mulamasah means that a man touches it (another's garment) with his hand and neither he unfolds it nor turns it over. When he touched it, the sale becomes binding.  

عَنِ النَّبِيِّ ﷺ بِهَذَا الْحَدِيثِ زَادَ وَاشْتِمَالُ الصَّمَّاءِ أَنْ يَشْتَمِلَ فِي ثَوْبٍ وَاحِدٍ يَضَعُ طَرَفَىِ الثَّوْبِ عَلَى عَاتِقِهِ الأَيْسَرِ وَيُبْرِزُ شِقَّهُ الأَيْمَنَ وَالْمُنَابَذَةُ أَنْ يَقُولَ إِذَا نَبَذْتُ إِلَيْكَ هَذَا الثَّوْبَ فَقَدْ وَجَبَ الْبَيْعُ وَالْمُلاَمَسَةُ أَنْ يَمَسَّهُ بِيَدِهِ وَلاَ يَنْشُرُهُ وَلاَ يُقَلِّبُهُ فَإِذَا مَسَّهُ وَجَبَ الْبَيْعُ  

The tradition mentioned above has also been transmitted by Abu Said al-Khudri through a different chain of narrators from the Messenger of Allah ﷺ to the same effect as narrated by both Sufyan and 'Abd al-Razzaq.  

نَهَى رَسُولُ اللَّهِ ﷺ بِمَعْنَى حَدِيثِ سُفْيَانَ وَعَبْدِ الرَّزَّاقِ جَمِيعًا  

The Messenger of Allah ﷺ forbade the transaction called habal al-habalah.  

أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنْ بَيْعِ حَبَلِ الْحَبَلَةِ  

Habal al-habalah means that a she-camel delivers an offspring and then the offspring which it delivers becomes pregnant.  

عَنِ النَّبِيِّ ﷺ نَحْوَهُ وَقَالَ حَبَلُ الْحَبَلَةِ أَنْ تُنْتَجَ النَّاقَةُ بَطْنَهَا ثُمَّ تَحْمِلُ الَّتِي نُتِجَتْ
