It is narrated from Sayyiduna Abu Umamah Bahili (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The links of Islam, that is, the commandments of Islam, will be undone one by one. When one link falls, people will pursue the next link. The first commandment to be broken will be justice, and the last to be demolished will be prayer (salah)."
