Blessed Days And Months
I agree! – as a reminder that it is never too late to ask for God’s forgiveness. – as a hope to cover up for the past sins. – as a motivation to do even more good deeds / Ibadah to earn even higher ranks in Jannah. – as a way to thank lord even more and to further solidify the relationship with Him. Thus a way, a reminder and an opportunity to achieve Tazkiya or to grow it even further.
Allah says he puts more blessings in them. Ie you will get more reward for good deeds
But giving gift is not part of justice system. The purpose of justice is fairness.. not to make people happy.
