Messenger of Allah, for whom I would give my father and mother in ransom, what do you recite during your period of silence between the takbir and the recitation? He said: I say (these words):" O Allah, remove my sins from me as Thou hast removed the East from the West. O Allah purify me from sins as a white garment is purified from filth. O Allah! wash away my sins with snow, water, and ice."  

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا كَبَّرَ فِي الصَّلاَةِ سَكَتَ هُنَيَّةً قَبْلَ أَنْ يَقْرَأَ فَقُلْتُ يَا رَسُولَ اللَّهِ بِأَبِي أَنْتَ وَأُمِّي أَرَأَيْتَ سُكُوتَكَ بَيْنَ التَّكْبِيرِ وَالْقِرَاءَةِ مَا تَقُولُ قَالَ أَقُولُ:

«اللَّهُمَّ بَاعِدْ بَيْنِي وَبَيْنَ خَطَايَاىَ كَمَا بَاعَدْتَ بَيْنَ الْمَشْرِقِ وَالْمَغْرِبِ اللَّهُمَّ نَقِّنِي مِنْ خَطَايَاىَ كَمَا يُنَقَّى الثَّوْبُ الأَبْيَضُ مِنَ الدَّنَسِ اللَّهُمَّ اغْسِلْنِي مِنْ خَطَايَاىَ بِالثَّلْجِ وَالْمَاءِ وَالْبَرَدِ.»  

Abu Huraira reported that when the Messenger of Allah ﷺ stood up for the second rak'ah he opened it with the recitation of the praise of Allah, the Lord of universe (al-Fatiha), and he did not observe silence (before the recitation of al-Fatiha).  

سَمِعْتُ أَبَا هُرَيْرَةَ يَقُولُ كَانَ رَسُولُ اللَّهِ ﷺ إِذَا نَهَضَ مِنَ الرَّكْعَةِ الثَّانِيَةِ اسْتَفْتَحَ الْقِرَاءَةَ بِ { الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ} وَلَمْ يَسْكُتْ  

A man came panting and entered the row of worshippers and said: Praise be to Allah, much praised and blessed. When the Messenger of Allah ﷺ finished the prayer he said: Who amongst you uttered these words? The people remained silent. He (the Prophet again said) -: Who amongst you uttered these words? He said nothing wrong. Then a man said: I came and had a difficulty in breathing, so I uttered them. He replied: I saw twelve angels facing one another as to who will take them up (to Allah).  

أَنَّ رَجُلاً جَاءَ فَدَخَلَ الصَّفَّ وَقَدْ حَفَزَهُ النَّفَسُ فَقَالَ الْحَمْدُ لِلَّهِ حَمْدًا كَثِيرًا طَيِّبًا مُبَارَكًا فِيهِ فَلَمَّا قَضَى رَسُولُ اللَّهِ ﷺ صَلاَتَهُ قَالَ أَيُّكُمُ الْمُتَكَلِّمُ بِالْكَلِمَاتِ فَأَرَمَّ الْقَوْمُ فَقَالَ أَيُّكُمُ الْمُتَكَلِّمُ بِهَا فَإِنَّهُ لَمْ يَقُلْ بَأْسًا فَقَالَ رَجُلٌ جِئْتُ وَقَدْ حَفَزَنِي النَّفَسُ فَقُلْتُهَا فَقَالَ لَقَدْ رَأَيْتُ اثْنَىْ عَشَرَ مَلَكًا يَبْتَدِرُونَهَا أَيُّهُمْ يَرْفَعُهَا  

While we said prayer with the Messenger of Allah ﷺ, one among the people said: Allah is truly Great, praise be to Allah in abundance. Glory be to Allah in the morning and the evening. The Messenger of Allah (may peace be upon, him) said: Who uttered such and such a word? A person among the people said: It is I, Messenger of Allah (who have recited these words). He (the Holy Prophet) said: It (its utterance) surprised me, for the doors of heaven were opened for It. Ibn 'Umar said: I have not abandoned them (these words) since I heard the Messenger of Allah ﷺ saying this.  

بَيْنَمَا نَحْنُ نُصَلِّي مَعَ رَسُولِ اللَّهِ ﷺ إِذْ قَالَ رَجُلٌ مِنَ الْقَوْمِ: (اللَّهُ أَكْبَرُ كَبِيرًا، وَالْحَمْدُ لِلَّهِ كَثِيرًا، وَسُبْحَانَ اللَّهِ بُكْرَةً وَأَصِيلاً) فَقَالَ رَسُولُ اللَّهِ ﷺ: «مَنِ الْقَائِلُ كَلِمَةَ» كَذَا وَكَذَا؟ قَالَ رَجُلٌ مِنَ الْقَوْمِ: أَنَا يَا رَسُولَ اللَّهِ! قَالَ: «عَجِبْتُ لَهَا فُتِحَتْ لَهَا أَبْوَابُ السَّمَاءِ۔» قَالَ ابْنُ عُمَرَ فَمَا تَرَكْتُهُنَّ مُنْذُ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ ذَلِكَ۔
