If Not Now Then When?

Qatādah رحمه الله: “Whoever does not have his sins forgiven in Ramaḍān, he will not have his sins forgiven in other than Ramaḍān..”

● [لطائف المعارف]

Meaning: If one did not take advantage of such great opportunity in Ramaḍān, more than likely he will not take advantage of any other opportunity to earn the forgiveness of Allāh.
