There following prayer, found at http://www.kashkul.org/2011/02/06/prayer-for-pregnancy/
I beseech Thee, O Lord of all being and Possessor of things visible and invisible, to bestow on me a righteous child so it may remember Thee on Thine earth and glorify Thee throughout Thy realm. If Thou maketh me by this tablet independent of every trace, fruit, and mention, my prayer at that time would be that which Thy chosen ones have uttered: “Lord, leave me not alone, for Thou art the best of Heirs.”
Baha’u'llah, quoted in Amr wa Khalq, 4:69. The quote is from Qur’an 21:89 in which Zechariah asks God to cure his wife’s infertility.
How to understand the words "every trace, fruit, and mention" in the prayer above?
