Gratefulness and ingratitude to Allah for His favors 29:65-69
29:65 When they embark upon ships, they call to Allah making their religion sincerely His; but when He brings them safe to the land, they associate others with Him
29:67 Do they not see how We appointed a safe Sanctuary while all around them people are snatched away? Would they believe in falsehood and do they disbelieve in the favor of Allah!
29:68 And who does greater evil than he who forges a lie against Allah or belied the truth when it comes to him! Is there not a lodging in Gehenna for the unbelievers?
