Khadija bint Khuwaylid

"what shows Khadija's piety is that when once one of her two sons died she was sad but patient. After a few hours the time of suckling the dead baby came and her breast was full of milk so her tears flowed from her eyes. Seeing this the Prophet was moved and said: if you so wish I shall ask Allah to make you hear his voice in Paradise. Any ordinary mother would have been keen to hear her dear one; but Khadija, may Allah be pleased with her said: 'no but I believe in Allah and his apostle'."

Allahuma Sallai Alla Muhammadin wa azwajihi wa zuriyatihi, kama sallayta alla Ibrahima wa alla ali Ibrahima fil alemina innaka hamidun majeed.
