The Prayer of Need
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 83
كَانَ عَلِيُّ بْنُ اَلْحُسَيْنِ عَلَيْهِمَا اَلسَّلاَمُ إِذَا حَزَنَهُ أَمْرٌ لَبِسَ ثَوْبَيْنِ مِنْ أَغْلَظِ ثِيَابِهِ وَ أَخْشَنِهَا ثُمَّ رَكَعَ فِي آخِرِ اَللَّيْلِ رَكْعَتَيْنِ حَتَّى إِذَا كَانَ فِي آخِرِ سَجْدَةٍ مِنْ سُجُودِهِ سَبَّحَ اَللَّهَ مِائَةَ تَسْبِيحَةٍ وَ حَمِدَ اَللَّهَ مِائَةَ مَرَّةٍ وَ هَلَّلَ اَللَّهَ مِائَةَ مَرَّةٍ وَ كَبَّرَ اَللَّهَ مِائَةَ مَرَّةٍ ثُمَّ يَعْتَرِفُ بِذُنُوبِهِ كُلِّهَا مَا عَرَفَ مِنْهَا أَقَرَّ لَهُ تَبَارَكَ وتَعَالَى بِهِ فِي سُجُودِهِ وَ مَا لَمْ يَذْكُرْ مِنْهَا اِعْتَرَفَ بِهِ جُمْلَةً ثُمَّ يَدْعُو اَللَّهَ عَزَّ وَ جَلَّ وَ يُفْضِي بِرُكْبَتَيْهِ إِلَى اَلْأَرْضِ.
When Ali ibn al-Hussain عليه السلام was troubled by a matter, he would wear two of his roughest and coarsest garments, then stand for two units of prayer in the last part of the night. When he reached the last prostration (Sujood), he would glorify Allah سبحانه وتعالى one hundred times, praise Allah سبحانه وتعالى one hundred times, declare the oneness of Allah سبحانه وتعالى (La ilaha illa Allah سبحانه وتعالى) one hundred times, and magnify Allah سبحانه وتعالى (Allahu Akbar) one hundred times. Then, he would acknowledge all of his sins — everything he remembered, he would confess before Allah سبحانه وتعالى, the Blessed and Exalted, during his prostration; what he could not recall, he would acknowledge in general. Thereafter, he would supplicate to Allah سبحانه وتعالى, the Mighty and Majestic, while placing his knees on the ground.
