Abu Abdullah (asws) said: ‘The one who complains of weakness, or headache, or urine blockage, should place his hand upon that particular place and should say: ‘اسْكُنْ سَكَّنْتُكَ بِالَّذِي سَكَنَ لَهُ مَا فِي اللَّيْلِ وَ النَّهَارِ وَ هُوَ السَّمِيعُ الْعَلِيمُ’ ‘Settle down for the Sake of the One for Whom (azwj) settle down what is in the night and the day, and He (azwj) the Hearing, the Knowing’.
