Not paying honestly


Narrated Abu Huraira:

The Prophet (ﷺ) said, “Allah said, ‘I will be an opponent to three types of people on the Day of Resurrection: -1. One who makes a covenant in My Name, but proves treacherous; -2. One who sells a free person and eats his price; and -3. One who employs a laborer and takes full work from him but does not pay him for his labor.’ ”

Pay the debts of dead


Narrated Salama bin Al-Akwa`:

A dead person was brought to the Prophet (ﷺ) so that he might lead the funeral prayer for him. He asked, “Is he in debt?” When the people replied in the negative, he led the funeral prayer. Another dead person was brought and he asked, “Is he in debt?” They said, “Yes.” He (refused to lead the prayer and) said, “Lead the prayer of your friend.” Abu Qatada said, “O Allah’s Messenger (ﷺ)! I undertake to pay his debt.” Allah’s Messenger (ﷺ) then led his funeral prayer.
