Hadith 4.1
Business Transactions
‘Umar reported God's Messenger as saying, "Gold for gold is usury unless both hand over on the spot*; silver for silver is usury unless both hand over on the spot; wheat for wheat is usury unless both hand over on the spot; barley for barley is usury unless both hand over on the spot; dates for dates is usury unless both hand over on the spot." (Bukhari and Muslim.) *"the Arabic is <i>ha’ waha’</i> meaning literally "take and take”.
وَعَنْ عُمَرَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الذَّهَبُ بِالذَّهَبِ رِبًا إِلَّا هَاءَ وَهَاءَ وَالْوَرِقُ بِالْوَرِقِ رِبًا إِلَّا هَاءَ وَهَاءَ وَالْبُرُّ بالبُرَّ إِلَّا هَاء وهاء وَالشعِير بِالشَّعِيرِ رَبًّا هَاءَ وَهَاءَ وَالتَّمْرُ بِالتَّمْرِ رِبًا إِلَّا هَاءَ وهاء»
