Ḥadiths that have been discussed in this paper consist of narrations regarding divine attributes and having some problematic meanings between supporters of Bishr al-Marīsī and ʿUthmān al-Dārimī. These narrations were mostly accepted denounced (munkar) by Bishr alMarīsī and his supporters due to having an anthropormophist and corporealist content about God. They rejected divine attributes according to their understanding of God based on incomparability (tanzīh) which provided by Muʿtazilite approach towards divine attributes even though they conveyed some features of Ahl al-Ra’y. They found contradicted of attributing human features to God based on their tanzīh understanding, therefore, they interpreted such this kind of narrations in terms of their approach or rejected at all. At the other hand, a hard Ḥadith scholar ʿUthmān al-Dārimī believed that one should accept divine attributes as they are in the Qurʾān and Sunna. According to his belief, he considered the explicit meanings of the narrations without interpretation of divine attributes, and based on his perspective he denied Bishr al-Marīsī (d. 218 /833) and his supporters’ interpretations claiming they would cause divesting God of all attributes (ṭaʿtīl). He argues that these narrations should be taken into considerations based on their explicit meanings. The discussions on these ḥadiths are important due to showing different approaches of scholars from the schools of Ahl al-Raʾy and the ones from Ahl al-Ḥadīth towards the ḥadith during the period when the main Ḥadith works were collected. Discussions on the narrations studied in this paper reveal two schools’ understandings of divine issues, their approaches to divine attributes, as well inform us their perspectives of ḥadith in general.

This paper presents the use of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method to determine the optimum process parameters in plasma arc cutting of stainless steel. Two input process parameters, cutting speed and plasma gas pressure are considered and experiments are conducted based on Taguchi L9 orthogonal array. After performing the experiments, the surface roughness, cut perpendicularity and kerf width are measured. The analysis of variance (ANOVA) are performed in order to identify the effect of each input process parameters on the output responses. The results indicate that TOPSIS method is appropriate for solving multi-criteria optimization of process parameters. Results also showed that cutting speed of 2500 mm/min and plasma gas pressure of 6 bar are the optimum combination of process parameters.
