Seek repentance & forgiveness after making mistakes , Remain patient while seeking mercy & grace from God Almighty & others around you despite their initial reactions/responses towards you .

This hadith is about Ka'b b. Malik who made a mistake by not joining the Prophet in the campaign of Tabuk and was consequently forbidden from speaking with other Muslims for an extended period of time. He eventually decided to go visit his cousin Abu Qatadah's garden and ask for forgiveness from him as well as God Almighty. This story teaches us that no matter how big our mistakes are or how long we have been away from seeking repentance or forgiveness; it is never too late to turn back towards God Almighty and seek His mercy and forgiveness through sincere repentance and patience in waiting for His response. It also teaches us that even if people around us do not forgive us right away or respond positively towards our efforts; we should still continue on our path with patience until we receive God's mercy which will come eventually if we remain steadfast on this path with sincerity in our hearts.
