Words of Prophet Muhammad (sallallahu ‘alaihi wa sallam)

Jabir bin ‘Abdullah (Radiya Allahu anhu) reported that the Messenger of Allah (PBUH) said:
“Satan erects his throne on water and sends his emissaries among the people. The closest person to him is the person who causes the most Fitnah. One of them (a devil) would come to him and would say, ‘I kept inciting so-and-so, until he said such and such words.’ Iblis says, ‘No, by Allah, you have not done much.’ Another devil would come to him and would say, ‘I kept inciting so-and-so, until I separated between him and his wife.’ Satan would draw him closer and embrace him, saying, ‘Yes, you did well.”
[Recorded by Imam Muslim 4:2167]

Sa’eed ibn Zaid reported: The Messenger of Allah, peace and blessings be upon him, said, “He who wrongly takes a span of land, Allah shall make him carry around his neck seven earths.”

[Sahih Muslim, Book 10, Number 3920]

Prophet Muhammad (sallallahu ‘alaihi wa sallam) said, “Whoever has wronged his brother, should ask for his pardon (before his death), as (in the Hereafter) there will be neither a Dinar nor a Dirham. (He should secure pardon in this life) before some of his good deeds are taken and paid to his brother, or, if he has done no good deeds, some of the bad deeds of his brother are taken to be loaded on him (in the Hereafter).
