Rajab is one of the sacred months Allah has selected. Allah says:

فلا تظلموا فيهن أنفسكم

“Do not wrong yourselves during them” (Al-Taubah: 36)

Scholars say there are 3 types of Dhulm (oppression):

1) Oppression regarding Allah – this is polytheism (shirk).

2) Oppression against others – taking their rights or hurting others.

3) Oppression against oneself – committing sins.

Therefore, our teachers remind us to strive to reduce sins as much as possible in this sacred month. Qatadah says ‘Injustice in these sacred months is *greater* in sin compared to other months…’ (Tafseer ibn Kathir).

Likewise the opposite is true – good deeds carry more weight when done in these months.
