Ibn 'Abbas said, "When one of you sneezes and says, 'Praise be to Allah,' the angel says, 'The Lord of the Worlds.' When you say, 'The Lord of the Worlds,' the angel says, 'May Allah have mercy on you.'"  

قَالَ الْمَلَكُ رَبَّ الْعَالَمِينَ فَإِذَا قَالَ رَبَّ الْعَالَمِينَ قَالَ الْمَلَكُ يَرْحَمُكَ اللَّهُ  

Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, "When one of you sneezes, he should say, 'Praise be to Allah,' and his brother or companion should say to him, 'May Allah have mercy on you.' Then he should say, 'May Allah guide you and put your affairs in order.'"
