Brihat Parashara Hora Shastra
चन्द्राच्चतुर्थगः पापो रिपुक्षेत्रे यदा भवेत्। तदा मातृवधं कुर्यात् केन्द्रे यदि शुभो न चेत्॥ २८॥
Should a malefic be in the 4th, identical with an inimical Rāśi, counted from Candr, while there is no benefic in a Kendra, the child will lose its mother in a premature manner.
