820. hadíth
وَقَالَ عَلَيْهِ اَلسَّلاَمُ: «إِنِّي لَأَعْجَبُ مِمَّنْ يَأْخُذُ فِي حَاجَةٍ وَ هُوَ عَلَى وُضُوءٍ كَيْفَ لاَ تُقْضَى حَاجَتُهُ وَ إِنِّي لَأَعْجَبُ مِمَّنْ يَأْخُذُ فِي حَاجَةٍ وَ هُوَ مُعْتَمٌّ تَحْتَ حَنَكِهِ كَيْفَ لاَ تُقْضَى حَاجَتُهُ.
Imam Jafar ibn Muhammad Al-Sadiq (a.s), said: "I am amazed by one who goes about seeking to fulfil a need while in a state of ritual purity (wudu) — how is it that his need is not met? And I am amazed by one who seeks to fulfil a need while wearing his turban wrapped under his chin — how is it that his need is not met?"
