Imam Ali (as) – The Valiant Ayah in focus – Surah Al-Adiyat (100: 1-5) This surah was revealed after the occurrence of the battle of Salasil. Rasulullah (saw) sent Imam Ali (as) to secure victory for the Muslims after the preceding group had returned defeated.
In the year eight after Hijrah, a group in a land called 'ard Yaabis',[The land of Yaabis] prepared an army of 12000 well armed men and their plan was to kill Rasul Allah, sall-Allahu 'alayhi wa alih, and Imam Ali 'alayhi as-salam.
When the Prophet, sall-Allahu 'alayhi wa alih, heard of their plans, he sent an army of 4000 men led by Abu Bakr, he was unable to fight them, so he came back. He then sent the 4000 men with 'Umar ibn al-Khattaab, he was still unable to fight them, so he came back. That is when Rasul Allah,sall-Allahu 'alayhi wa alih, sent the 4000 men with Amir ul-Mu'minin, Ali ibn abi Taalib, who took those men riding their horses at night on the rocks and therefore the hooves of their horses, which has horseshoes, the metal striking on the rocks was creating sparks.
He comes and he meets those individuals, they said, Who are you? He said, I am Ali ibn Abu Talib. They said, 'you are the one whom we are looking for and we want to fight and kill you'. He says, 'I am offering you Islam.' They said, 'No!'. He said, 'How about peace? Go back.' They said, 'No! Only war tomorrow morning.'
So in the morning Amir ul-Mu'minin 'alayhi as-salam, prays Salaat al-Fajr and goes and surrounds them all. When they wake up to get ready to the battle, they find that Amir ul-Mu'minin had already surrounded them. A few of them got killed, he captures the others and brought a lot of booty to the Muslims. Imam Al-Sadiq 'alayhi as-salam, says, "That booty was not less than the booty the Muslims collected in Khaybar".
This battle became known as 'dhaat us-salaasil', and Surat al-Adiyat was revealed to Rasul Allah sall-Allahu 'alayhi wa alih, before the arrival of Amir ul-Mu'minin 'alayhi as-salam, were the verses go as follows: "By the snorting chargers, [the horses], ...by the strikers of sparks [with their hoofs] by the raiders at dawn [when Imam Ali raided them at dawn],... raising therein a trail of dust, [as they were riding these horses, dust was rising]...and cleaving therein a host"(100:1-5). And that is how Imam Ali brought victory salam Ullahi 'alayh.
Wa as-salamu 'alaykum, wa Rahmat Ullahi, wa barakaatuh.
