The distinction between Islam and Iman (faith), and the proof for that from the Book of Allah, the Sunnah of His Messenger (peace and blessings of Allah be upon him), and the sayings of the Companions and the Successors.
التَّفْرِيقُ بَيْنَ الْإِسْلَامِ وَالْإِيمَانِ وَالْحُجَّةُ فِي ذَلِكَ مِنْ كِتَابِ اللَّهِ، وَسُنَّةِ رَسُولِهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ، وَأَقْوَالِ الصَّحَابَةِ، وَالتَّابِعِينَ
