أثرُ السُّجودِ The Effect of Prostration

8ـ الإمامُ عليٌّ (عَلَيهِ الّسَلامُ): إنّي لأكرَهُ للرَّجُلِ أن تُرى جَبهَتُهُ جَلحاءَ لَيسَ فيها شيءٌ مِن أثَرِ السُّجودِ.

8– Imam Ali (AS) said, 'I hate it for a man to have a smooth forehead not having any trace of prostration on it.’[Bihar al-Anwar, v. 71, p. 344, no. 4]
 

9ـ الإمامُ الباقرُ (عَلَيهِ الّسَلامُ): كانَ لأبِي (عَلَيهِ الّسَلامُ) في مَوضِعِ سُجودِهِ آثارٌ ناتِيةٌ ، وكانَ يَقطَعُها في السَّنَةِ مَرَّتَينِ ، في كُلِّ مَرّةٍ خَمسَ ثَفِناتٍ فَسُمِّيَ ذا الثَّفِناتِ لذلكَ.

9– Imam al-Baqir (AS) said, 'My father (AS) used to have protruding marks from prostration on his forehead, which he used to cut twice a year, and every time he would do so, he would scrape off five calluses, and came to be nicknamed 'the one with calluses.’[`AeIlal al-Shara’i`a , p. 233, no. 1]
