[Machine] He used to give a sermon when Ramadan approached and then he would say, "This blessed month is the one in which Allah has obligated fasting and did not obligate standing in prayer. Let a person be cautious against saying, 'I am fasting' when someone else is fasting, or 'I have broken my fast' when someone else has broken their fast. Verily, fasting is not merely abstaining from food and drink, but it is also refraining from lying, falsehood, and vain talk. So do not begin the month until you see the crescent moon, then fast when you see it and break your fast when you see it. But if it is cloudy for you, then complete the count of thirty days." He used to say this after the Fajr prayer and the Asr prayer. And Abu al-Fath informed us that al-Husayn narrated to us, from Ibrahim, from Hushaym, from Mujalid, from al-Sha'bi, from Masruq, that Umar used to say something similar to that.  

أَنَّهُ كَانَ يَخْطُبُ إِذَا حَضَرَ رَمَضَانُ ثُمَّ يَقُولُ هَذَا الشَّهْرُ الْمُبَارَكُ الَّذِي فَرَضَ اللهُ صِيَامَهُ وَلَمْ يَفْرِضْ قِيَامَهُ لِيَحْذَرْ رَجُلٌ أَنْ يَقُولَ أَصُومُ إِذَا صَامَ فُلَانٌ أَوْ أُفْطِرُ إِذَا أَفْطَرَ فُلَانٌ أَلَا إِنَّ الصِّيَامَ لَيْسَ مِنَ الطَّعَامِ وَالشَّرَابِ وَلَكِنْ مِنَ الْكَذِبِ وَالْبَاطِلِ وَاللَّغْوِ أَلَا لَا تَقَدَّمُوا الشَّهْرَ إِذَا رَأَيْتُمُ الْهِلَالَ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَأَكْمِلُوا الْعِدَّةَ قَالَ كَانَ يَقُولُ ذَلِكَ بَعْدَ صَلَاةِ الْفَجْرِ وَصَلَاةِ الْعَصْرِ 7956 وَأَخْبَرَنَا أَبُو الْفَتْحِ أنبأ الْحُسَيْنُ ثنا إِبْرَاهِيمُ ثنا هُشَيْمٌ عَنْ مُجَالِدٍ عَنِ الشَّعْبِيِّ عَنْ مَسْرُوقٍ أَنَّ عُمَرَ ؓ كَانَ يَقُولُ مِثْلَ ذَلِكَ
