From Malik bin Aws bin Hadathan that he said: "I once said: 'Who can change some Dirham?' So Talhah bin 'Ubaidullah - and he was with 'Umar bin Al-Khattab - said: "Leave your gold with us, then return to us when our servant comes and we will give you your silver." 'Umar bin Al-Khattab said: "No! By Allah! Either give him his silver or return his gold to him. Indeed the Messenger of Allah (ﷺ) said: 'Silver for gold is Riba, except for hand to hand; and wheat for wheat is Riba except for hand to hand; and barley for barley is Riba except hand to hand; and dried-dates for dried-dates is Riba except for hand to hand.'"

[Abu 'Eisa said:] This Hadith is Hasan Sahih. This is acted upon according to the people of knowledge. And the meaning of Ha' Wa Ha' is hand to hand.
