Question Detail:

I heard in a talk by an Imam that the jews in occupied Palestine said when the masajid is full for Fajr salah the Promised land will come back to the muslims due to the fact that we the muslims have regained our iman, is this true or false? 

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
Brother in Islam,
You may refer to the Imam in reference for further clarity on his statement. Nevertheless, Allah Ta’ala says:
وَعَدَ اللَّهُ الَّذِينَ آمَنُوا مِنْكُمْ وَعَمِلُوا الصَّالِحَاتِ لَيَسْتَخْلِفَنَّهُمْ فِي الْأَرْضِ كَمَا اسْتَخْلَفَ الَّذِينَ مِنْ قَبْلِهِمْ 
Allah Ta’ala has promised those of you who have Imaan and do good actions that he will definitely make them successors (of the rulers) on earth just as had made those before them. (Surah Noor: 55)   
As Muslims we should strengthen our Imaan and do righteous deeds to invoke the mercy of Allah Ta’ala.
To achieve this, every individual should take it upon himself to reform himself and be Allah conscience.
And Allah Ta’āla Knows Best
