Today, we had the opportunity to talk with a brother who turned towards Allah just 13 days ago. He was saying that: Look at a car. After few years of driving you have to change the tires. But look at your feet, all your life you walk with them but don't need to keep changing them. Then look at the joints of machines. If they are not regularly lubricated using chemicals, then you will hear annoying scratching sounds coming out of them. But look your joints in the body, we never lubricate them yet they function perfectly without making any scratching sounds. These are indeed the signs of Allah.
"Lo! In the creation of the heavens and the earth and (in) the difference of night and day are signs (of His Sovereignty) for men of understanding..." Surah Al Imran verse 190.
