What does the Muslim say when he sees someone afflicted by a calamity?

الْحَمْدُ لِلَّهِ الَّذِي عَافَانِي مِمَّا ابْتَلَاكَ بِهِ، وَفَضَّلَنِي عَلَى كَثِيرٍ مِمَّنْ خَلَقَ تَفْضِيلًا

All praise is for Allah Who saved me from what He tested you with and Who most certainly favored me over much of His creation.
