QuranLab — Qur'an and Hadith Training Mix
Training-ready data derived from the QuranLab corpora: continued-pretraining text,
grounded instruction data, preference pairs, verifiable prompts, retrieval pairs and
a held-out evaluation set — all built on the same verse and ḥadīth keys as
quranlab/quran and
quranlab/hadith.
QuranLab is a volunteer effort. Our aim is to present these works carefully and at high quality, and to help them travel faithfully — in the spirit in which they… See the full description on the dataset page: https://huggingface.co/datasets/quranlab/islamic-llm-training.Turkish-LLM-v10-Training
