Everyone of us learn different things /lessons on daily basis but few people remember the learnt things/lessons. We human beings are the most forgetful and ungrateful. In the Holy Qur'an, Allah says that human is very ungrateful and hasty. (Meaning) When I reached the gate of the office in the morning, the receptionist asked, "Sir, did you hear about Arsalan Sahib?" I asked what happened? He replied that Arsalan sahib had died in the night, he had a heart attack. I was shocked because I greeted him last evening, he was in good health. This death made me think that we are mortal, we have to go back to Allah but we are busy with worldly pleasures and have forgotten the reality like death. We must think that we too will die one day because this world and life is temporary. How many people are hurt every day, how many people are deprived of their rights by us and do not even apologize. When death comes, there is no time to apologize and repent.
