I've been reading the biography of the Prophet SAW, called the Sealed Nectar
There's one part where a certain tribe killed 70 of the prophet SAW's companions, It says
Anas reported that for thirty days the Prophet SAW suplicated Allah against those who killed his companions at Ma'una Well. Every dawn prayer he would invoke Allah's wrath against Ri'l, Dhakwan, Lihyan and 'Usaiyah. He would say "Usaiyah disobeyed Allah and his Messenger" Therefore Allah sent down unto us His Messenger a Qu'ranic verse that we kept reciting till it was abrogated later on 'Inform our folk that we have encountered our Lord and he is satisfied with us and we are satisfied with Him' So the messenger of Allah SAW stopped his invocation.
Its from Sahih Bukhari 2/586-588. If anyone has the english translation its on page 301
I'm quite sure i've misunderstood what it's said, so can someone please help?
