Hawzah News Agency - Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus from Husayn ibn al-Mundhir from ‘Umar ibn Qays from abu Ja’far who has said the following. “I heard Imam abu Ja‘far saying,

إِنَّ الله تَبَارَكَ وَتَعَالَى لَمْ يَدَعْ شَيْئاً يَحْتَاجُ إِلَيْهِ الامَّةُ إِلا أَنْزَلَهُ فِي كِتَابِهِ وَبَيَّنَهُ لِرَسُولِهِ ص وَجَعَلَ لِكُلِّ شَيْ‏ءٍ حَدّاً وَجَعَلَ عَلَيْهِ دَلِيلاً يَدُلُّ عَلَيْهِ وَجَعَلَ عَلَى مَنْ تَعَدَّى ذَلِكَ الْحَدَّ حَدّاً.

‘Allah, the Most holy, the Most high, has not left untold anything that the ’ummah would need except that He has revealed in His book and has explained them to His messenger. He has made a limit for everything and an indication for it to point forwards to it and He has made a limit for those who would trespass those limits.”
