Saleh, a resident of Shabwa in the Yemen, dreamed so often that he was growing a horn on his head that he came to bel­ieve it would come to pass. It was only a quest­ion of when. Now aged 102, he recounts how a horn began to sprout on the left side of his head 25 years ago.

Since it did not bother him and there were no local medical facilities, he just ig­nored it. Event­ually, it grew into a horn 1ft 8in (50cm) long. His fell­ow vill­ag­ers were as­tound­ed and ass­umed it must be pain­ful, but Saleh said they came to real­ise it was simply “some­thing Allah wanted to happen to show the people that he can do as he de­sires”.
