Aisha said, "Barirah came to me and said, 'My people (masters) have written the contract for my
emancipation for nine Awaq ) of gold) to be paid in yearly installments, one Uqiyya per year; so help
me." Aisha said (to her), "If your masters agree, I will pay them the whole sum provided the Wala will
be for me." Barirah went to her masters and told them about it, but they refused the offer and she
returned from them while Allah's Messenger (ﷺ)s was sitting. She said, "I presented the offer to them, but
they refused unless the Wala' would be for them." When the Prophet (ﷺ) heard that and `Aisha told him
about It, he said to her, "Buy Barirah and let them stipulate that her Wala' will be for them, as the
Wala' is for the manumitted." `Aisha did so. After that Allah's Messenger (ﷺ) got up amidst the people,
Glorified and Praised Allah and said, "What is wrong with some people who stipulate things which
are not in Allah's Laws? Any condition which is not in Allah's Laws is invalid even if there were a
hundred such conditions. Allah's Rules are the most valid and Allah's Conditions are the most solid.
The Wala is for the manumitted."
Sahih al-Bukhari Book 54, Hadith 17
One day the Messenger of Allah (ﷺ) entered the mosque. He saw there a man from the Ansar called AbuUmamah.
He said: What is the matter that I am seeing you sitting in the mosque when there is no time of prayer?
He said: I am entangled in cares and debts, Messenger of Allah.
He replied: Shall I not teach you words by which, when you say them, Allah will remove your care, and settle your debt?
He said: Why not, Messenger of Allah?
He said: Say in the morning and evening: "O Allah, I seek refuge in Thee from care and grief, I seek refuge in Thee from incapacity and slackness, I seek refuge in Thee from cowardice and niggardliness, and I seek in Thee from being overcome by debt and being put in subjection by men."
He said: When I did that Allah removed my care and settled my debt.
Sunan Abi Dawud Book 8, Hadith 140
