حَدَّثَنَا أَبُو سَعِيدٍ حَدَّثَنَا زَائِدَةُ حَدَّثَنَا مَنْصُورٌ عَنْ شَقِيقٍ عَنْ عَبْدِ اللَّهِ قَالَ كُنَّا إِذَا صَلَّيْنَا خَلْفَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ الرَّجُلُ مِنَّا فِي صَلَاتِهِ السَّلَامُ عَلَى اللَّهِ السَّلَامُ عَلَى فُلَانٍ يَخُصُّ فَقَالَ لَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ذَاتَ يَوْمٍ إِنَّ اللَّهَ عَزَّ وَجَلَّ هُوَ السَّلَامُ فَإِذَا قَعَدَ أَحَدُكُمْ فِي صَلَاتِهِ فَلْيَقُلْ التَّحِيَّاتُ لِلَّهِ وَالصَّلَوَاتُ وَالطَّيِّبَاتُ السَّلَامُ عَلَيْكَ أَيُّهَا النَّبِيُّ وَرَحْمَةُ اللَّهِ وَبَرَكَاتُهُ السَّلَامُ عَلَيْنَا وَعَلَى عِبَادِ اللَّهِ الصَّالِحِينَ فَإِذَا قُلْتُمْ ذَلِكَ فَقَدْ سَلَّمْتُمْ عَلَى كُلِّ عَبْدٍ فِي السَّمَوَاتِ وَالْأَرْضِ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ ثُمَّ يَتَخَيَّرُ بَعْدُ مِنْ الدُّعَاءِ مَا شَاءَ أَوْ مَا أَحَبَّ
مسند امام احمد بن حنبل · Hadith 3919
It was narrated that 'Abdullah (RA) said: When we prayed behind the Messenger of Allah (PBUH), one o( us would say in his prayer: Peace be upon Allah, peace be upon So and so, mentioning some specific names. Then the Messenger of Allah (PBUH) said to us one day: "Allah, may He be glorified and exalted, is as Salam, so when one of you sits in his prayer, let him say: 'All compliments, prayers and pure words arc due to Allah. Peace be upon you, O Prophet, and the mercy of Allah and His blessings. Peace be upon us, and on the righteous slaves of Allah' - If you say that, you will have sent salams upon every slave (of Allah) in the heavens and on earth - 'I bear witness that there is no god but Allah, and I bear witness that Muhammad is His slave and Messenger’. Then let him choose whatever supplication he wants or he likes."
