Sunan Ibn Majah Book 33, Hadith 162
the Prophet (saas) said: "Glad tidings to those who find a lot of seeking forgiveness in the record of their deeds."
"I was harsh in the way I spoke to my family, but not to others. I mentioned that to the Prophet (saas) and he said: 'Why don't you ask for forgiveness? Ask Allah to forgive you, seventy times each day.'"
the Messenger of Allah said: "Whoever persists in asking for forgiveness, Allah will grant him relief from every worry, and a way out from every hardship, and will grant him provision from (sources) he could never imagine."
