It is narrated from Sayyidah Juwayriyah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) passed by her when he (peace and blessings be upon him) had prayed the Fajr prayer, or after it, while she was engaged in the remembrance of Allah. Then the day advanced and she was still in that state. So he (peace and blessings be upon him) said: "Since I got up from you, I have said some words three times each that are greater and heavier, or weightier, than what you have said: 'Subhan Allahi adada khalqihi' (Glory be to Allah, as many times as the number of His creation), 'Subhan Allahi rida nafsihi' (Glory be to Allah, as much as pleases Him), 'Subhan Allahi zinata arshihi' (Glory be to Allah, as much as the weight of His Throne), 'Subhan Allahi midada kalimatihi' (Glory be to Allah, as much as the ink of His words)."
