(37) باب بَيْعِ السِّلاَحِ فِي الْفِتْنَةِ وَغَيْرِهَا
Narrated Abu Qatada:
We set out with Allah's Messenger (ﷺ) in the year of Hunain, (the Prophet (ﷺ) gave me an armor). I sold that armor and bought a garden in the region of the tribe of Bani Salama and that was the first property I got after embracing Islam.
