Mishkat al-Masabih #2215

Busaira, who was one of the women emigrants, told of God’s messenger saying to them, “Apply yourselves to glorifying God, saying there is no god but He, and declaring His holiness; and count them on your fingers, for they will be questioned and asked to speak; and do not be negligent and so be deprived of mercy.” Tirmidhi and Abu Dawud transmitted it.
