It is narrated from Sayyiduna Abu Malik al-Ash'ari (may Allah be pleased with him) that the Prophet of Allah (peace and blessings be upon him) said: "The greatest betrayal (ghulul) with Allah on the Day of Resurrection is a cubit of land - or he said: a handspan - which a man steals from his neighbour, in that there is land between the two of them and one of them steals it from the other; then he will be made to wear it as a collar from seven earths."
