A top Iman has told Muslims to use the migrant crisis to breed with European citizens and 'conquer their countries'.

Sheikh Muhammad Ayed gave the speech at the Al-Aqsa Mosque in Jerusalem claiming Europe was only welcoming refugees as a new source of labour.

He said Europe was facing a demographic disaster and urged Muslims to have children with westerners so they could 'trample them underfoot, Allah willing.'

'Throughout Europe, all the hearts are enthused with hatred toward Muslims. They wish that we were dead, but they have lost their fertility, so they look for fertility in our midst,' Infowars reports.

'We will give them fertility. We will breed children with them, because we shall conquer their countries.'

In the full video, he said Americans, Italians, Germans and the French will be forced to take refugees.

Italy has the lowest birth rate since 1861 with 8.4 per 1,000 people and much or Europe is following the same trend.

Claims: Sheikh Muhammad Ayed said Europe was only taking refugees as a new source of labour

Birth rates are far higher in the Middle East and Sub-Saharan Africa, which is where most migrants are coming from.

The notion of using mass migration as a form of stealth jihad is outlined in the Koran, which states, 'And whoever emigrates for the cause of Allah will find on the earth many locations and abundance.'
