وَ رُوِيَ عَنْ عَبْدِ اَلْمَلِكِ بْنِ أَعْيَنَ قَالَ: قُلْتُ لِأَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ إِنِّي قَدِ اُبْتُلِيتُ بِهَذَا اَلْعِلْمِ فَأُرِيدُ اَلْحَاجَةَ فَإِذَا نَظَرْتُ إِلَى اَلطَّالِعِ وَ رَأَيْتُ اَلطَّالِعَ اَلشَّرَّ جَلَسْتُ وَ لَمْ أَذْهَبْ فِيهَا وَ إِذَا رَأَيْتُ اَلطَّالِعَ اَلْخَيْرَ ذَهَبْتُ فِي اَلْحَاجَةِ فَقَالَ لِي «تَقْضِي » قُلْتُ نَعَمْ قَالَ «أَحْرِقْ كُتُبَكَ».
It is narrated from Abdul Malik ibn A'yan who said: "I said to Abu Abdullah (a.s) 'I have been tested with this knowledge (of astrology). When I intend to fulfill a need and observe the rising star, if I see it as unfavorable, I sit and do not proceed. But if I see it as favorable, I proceed with my need.' Imam (a.s) said to me: 'Do you accomplish it?' I said: 'Yes.' Imam (a.s) said: 'Burn your books.'"
