ḤADĪTH OF THE DAY

“ The Prophet, peace and blessings of God be upon him said, "Gabriel led me in prayer at the house (1) two times (on two consecutive days). He prayed the noon prayer (2), the first time, when the shadow was the size of a shoe strap (the shortest shadow that could be observed). Then, he prayed the afternoon prayer (3) when everything was as long as its shadow. Then, he prayed the sunset prayer (4) when the sun set, the time when a fasting person breaks his [or her] fast. Then, he prayed the evening prayer (5) when the twilight disappeared. Then, he prayed the dawn prayer (6) when dawn broke, the time when food becomes prohibited for a fasting person. The second time, he prayed the noon prayer until the shadow of everything was equal to its length, the time at which he had prayed the afternoon prayer the day before (7). Then, he prayed the afternoon prayer when the shadow of everything was twice its length. Then, he prayed the sunset prayer at the same time as the day before. Then, he prayed the last evening prayer when one third of the night had passed. Then he prayed the dawn prayer when the earth shone with light. Then Gabriel turned to me and said, 'O Muhammad, thus was the timing (of prayer) for the prophets before you (8). The time [of each prayer] is between these two times (at which we prayed on each of the two days).'" Footnotes: (1) the sanctified house of God (al-Ka'bah) which is the most venerable structure in Islam, situated within in the Sanctified Mosque of Makkah. During prayer, Muslims face its direction, wherever they are in the world. (2) Second prescribed prayer of the day. (3) Third prescribed prayer of the day. (4) Fourth prescribed prayer of the day. (5) Fifth prescribed prayer of the day. (6) First prescribed prayer of the day. (7) He finished the noon prayer on the second day at the same time that he had started the afternoon prayer the first day. (8) i.e. The prayers of the prophets before you had extended times like these. ”

Sunan at-Tirmithiy كتاب الطهارة باب الوضوء من مس الذكر

حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ قَالَ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ الْقَطَّانُ عَنْ هِشَامِ بْنِ عُرْوَةَ قَالَ أَخْبَرَنِى أَبِى عَنْ بُسْرَةَ بِنْتِ صَفْوَانَ أَنَّ النَّبِىَّ صلى الله عليه وسلم قَالَ مَنْ مَسَّ ذَكَرَهُ فَلاَ يُصَلِّ حَتَّى يَتَوَضَّأَ. قَالَ وَفِى الْبَابِ عَنْ أُمِّ حَبِيبَةَ وَأَبِى أَيُّوبَ وَأَبِى هُرَيْرَةَ وَأَرْوَى ابْنَةِ أُنَيْسٍ وَعَائِشَةَ وَجَابِرٍ وَزَيْدِ بْنِ خَالِدٍ وَعَبْدِ اللَّهِ بْنِ عَمْرٍو. قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ. قَالَ هَكَذَا رَوَاهُ غَيْرُ وَاحِدٍ مِثْلَ هَذَاعَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ عَنْ بُسْرَةَ.
The Prophet, peace and blessings of God be upon him, said, "Whoever touches his private parts (i.e. directly, without a barrier of cloth) must not pray until he performs ablution".
