Layth reported: Mujahid, may Allah have mercy on him, said, “Whoever is safe from two characteristics will secure his fasting: backbiting and falsehood.”
Al-Bayhaqi said, “Just as one guards his fasting from what is not befitting, one must guard himself in the month of Ramadan to obey Allah as much as possible.”

عَنْ لَيْثٍ عَنْ مُجَاهِدٍ رَحِمَهُ اللَّهُ قَالَ خَصْلَتَانِ مَنْ حَفِظَهُمَا سَلِمَ لَهُ صَوْمُهُ الْغِيبَةُ وَالْكَذِبُ
قَالَ الشَّيْخُ رَضِيَ اللَّهُ عَنْهُ وَكَمَا يَحْتَرِزُ فِي صِيَامِهِ عَمَّا لَا يَلِيقُ بِهِ يَجْتَهِدُ فِي شَهْرِ رَمَضَانَ فِي طَاعَةِ اللَّهِ مَا أَمْكَنَهُ
