4. Ja’far ibn Muḥammad ibn Ibrāhīm ibn ‘Ubaydillāh ibn Mūsā Al-Kāżim عليه السلام ibn Jafar Al-Sādiq عليه السلام, narrated to me from ‘Ubaydillāh ibn Nahīk, from Muḥammad ibn Ziyād, from Abī Ḥanīfah Al-Sābiq, from Yūnus ibn ‘Ammār, who said: Abū ‘Abdillāh (Imam Sādiq عليه السلام) said: If you are close (in proximity) to him – referring to Ḥusain عليه السلام – and it is possible to perform Ghusl before going to him, do so. Otherwise, perform Wuďū and then go to him.
