It is narrated from the Prophet of Islam (PBUH) who said: O’ the group of Mohajeroon, There are five conditions which I do not want you be in.
1.Whenever a tribe/nation commits immodest and immoral acts, illnesses such as plague and other illnesses which did not exist in the past generations will spread among them.
2.Whenever a nation reduce the weight and measure (sell underweight) will be inflicted with famine and poverty, and the oppression of the rulers.
3.Whenever a tribe/nation avoids paying Zakat, will be deprived from rain, and if it was not for the sake of animals, it would never rain.
4.Whenever a tribe/nation break covenant with God and the Prophet (PBUH), God will make foreign enemies dominate them to rub their wealth.
5.Whenever the leaders do not act upon the book of God, and do not adopt whatever has been sent by God; God will inflict war and disputes among them [1].
