“Do you
intend to perform Hajj this year?” He said: “Yes.”
She said: “Pray to
Allah for us to grant us goodness, for the
Prophet (ﷺ) used to say:
‘The supplication of a man for his
brother in his absence will be
answered. By his head there is an
angel who says Amin to his
supplication, and every time he prays for
his brother, he says: “Amin,
and the same for you.’” He said:
“Then I went out to the marketplace
where I met Abu Darda’, and
he told me something similar from the
Prophet (ﷺ).”
