بِسْمِ اللّهِ الرَّحْمـَنِ الرَّحِيمِ
فَقُلْتُ اسْتَغْفِرُوا رَبَّكُمْ إِنَّهُ كَانَ غَفَّارًا
يُرْسِلِ السَّمَاء عَلَيْكُم مِّدْرَارًا وَيُمْدِدْكُمْ بِأَمْوَالٍ وَبَنِينَ وَيَجْعَل لَّكُمْ جَنَّاتٍ وَيَجْعَل لَّكُمْ أَنْهَارًا
يُرْسِلِ السَّمَاء عَلَيْكُم مِّدْرَارًا وَيُمْدِدْكُمْ بِأَمْوَالٍ وَبَنِينَ وَيَجْعَل لَّكُمْ جَنَّاتٍ وَيَجْعَل لَّكُمْ أَنْهَارًا
Nuh 71:10-12. and I said: "Ask your Sustainer to forgive you your sins - for, verily, He is all-forgiving!He will shower upon you heavenly blessings abundant, and will aid you with worldly goods and children, and will bestow upon you gardens, and bestow upon you running waters.
Seek Forgiveness from Allah and rely on Him for your needs
Imam Ahmed bin Hanbal, may Allah be pleased with him, a renowned scholar of Islam and a famous theologian, once was passing through a remote town. Owing to his humility, he had not introduced himself to anyone. After salah, he wanted to stay overnight at the masjid, but the caretaker as a matter of policy ( and also not recognizing who he was) asked him to leave. Imam Ahmed tried to convince him to let him stay, but of no avail, and the caretaker literally dragged the aging imam out. A man, who worked as a baker, was passing by and watched this scene and (as any good Muslim should), offered to host him for the night.
While at the baker's place, the Imam saw him engrossed in his work, mixing and kneading the dough, tending the fire, and pulling loaves from the oven, all the while doing dhikr, especially Istighfar (asking for Allah's forgiveness).
The Imam asked the baker if he has experienced any blessings due to reciting the same, and the baker replied: "By Allah! No do'a (supplication) I have ever made has been unanswered, except one."
“And what is that do'a?” asked Imam Ahmed.
The baker responded: "To see the renowned Imam Ahmad ibn Hanbal." Upon hearing this, tears welled up in his eyes as he disclosed to the baker, "I am Ahmed ibn Hanbal! By Allah! I was dragged to your place so that your do'a would be fulfilled."
The impact of istighfar
Someone complained to Al-Hasan Al-Basri about a drought, and he said to him: "Seek forgiveness from Allah. Someone else complained to him of poverty and he said to him: "Ask Allah to forgive you." Someone else had the concern of gardens going dry, and yet another had no children, and in all of these cases, Hasan advised the same "Ask Allah for forgiveness."
He was asked about this cure-all and he replied: "I do not say this out of my own accord, for does Allah not say in Surah Nuh:"
"Ask your Sustainer to forgive you your sins - for, verily, He is all-forgiving! He will shower upon you heavenly blessings abundant, and will aid you with worldly goods and children, and will bestow upon you gardens, and bestow upon you running waters.
A modern story, similar to that of Imam Ahmed, but about the power of do'a is narrated by Mufti Ismail Menk in the following video:
