Make frequent prostrations to Allah, for you do not make a single prostration to Allah except that Allah raises you one degree therewith and remits one sin from you therewith

عَنْ مَعْدَانَ بْنِ أَبِي طَلْحَةَ الْيَعْمَرِيُّ قَالَ: لَقِيتُ ثَوْبَانَ مَوْلَى رَسُولِ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ، فَقُلْتُ: أَخْبِرْنِي بِعَمَلٍ أَعْمَلُهُ يُدْخِلُنِي اللهُ بِهِ الْجَنَّةَ؟ أَوْ قَالَ قُلْتُ: بِأَحَبِّ الْأَعْمَالِ إِلَى اللهِ، فَسَكَتَ. ثُمَّ سَأَلْتُهُ فَسَكَتَ. ثُمَّ سَأَلْتُهُ الثَّالِثَةَ فَقَالَ: سَأَلْتُ عَنْ ذَلِكَ رَسُولَ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ، فَقَالَ: «عَلَيْكَ بِكَثْرَةِ السُّجُودِ لِلَّهِ، فَإِنَّكَ لَا تَسْجُدُ لِلَّهِ سَجْدَةً، إِلَّا رَفَعَكَ اللهُ بِهَا دَرَجَةً، وَحَطَّ عَنْكَ بِهَا خَطِيئَةً» قَالَ مَعْدَانُ: ثُمَّ لَقِيتُ أَبَا الدَّرْدَاءِ فَسَأَلْتُهُ فَقَالَ لِي: مِثْلَ مَا قَالَ لِي: ثَوْبَانُ.

Ma‘dān ibn Abi Talhah al-Ya‘mari reported: I met Thawbān, the freed slave of the Messenger of Allah (may Allah's peace and blessings be upon him), and he said: Tell me about a deed to perform by virtue of which Allah admits me to Paradise - or he said: I said: about the deeds that Allah loves most - but he remained silent. Then I asked him, but he remained silent. Then I asked him for the third time, and he said: I asked the Messenger of Allah (may Allah's peace and blessings be upon him) about this, and he said: "Make frequent prostrations to Allah, for you do not make a single prostration to Allah except that Allah raises you one degree therewith and remits one sin from you therewith." Ma‘dān said: Then I met Abu ad-Dardā’ and I asked him and he told me the same as Thawbān.
