Al-Zalzalah/The Earthquak
I/We begin by the Blessed Name of Allah
The Immensely Merciful to all, The Infinitely Compassionate to everyone.
99:01
a. When the earth will be shaken violently in its mighty quaking to its very core,
99:02
a. and when the earth will throw out its burdens of the dead from their graves,
99:03
a. and when the human being will be crying out in panic:
b. ‘What is happening to it?’
99:04
a. At that Time it - the earth - will narrate its news,
99:05
a. for your Rabb - The Lord would have commanded it to do so.
99:06
a. That Time the people will proceed in separate groups,
b. so that they may be shown the results of their worldly deeds and dealings.
99:07
a. So whoever would have done good, even to the weight of a particle, will see it, and be rewarded for it.
99:08
a. And whoever would have done evil, even to the weight of a particle, will see it, and be rewarded for it.
There are several points which illustrate Qur’ānic I‘jāz and probably rely on Islamic Theologians -Mutakallimin’s- efforts as well as exertions regarding Qur’ānic I‘jāz. Mutakallimin for having good command over Arabic rhetorical structures have demonstrated Qur’ānic I‘jāz in two contexts: theoretically and empirically. They actually validated, that Qur’ān is the book of Allah Almighty, through comparing both standard Arabic texts: prose and poetry into face of Qur’ānic text. All these cherished efforts of Mutakallimin are rooted in Arabic rhetoric which stands for that Arabic Rhetoric and ‘ilm al-Kalām; both have very primary relation resulting in that cannot be ignored while analyzing I‘jāz phenomenon.
The selection of dyes and dyeing auxiliaries is a crucial factor in optimising dyeing processes. Dyeings often show unsatisfactory wet fastness properties. This is usually encountered with direct dyes and to a lesser extent with reactive dyes also. Different cationic fixing agents have been used as pretreatment or aftertreatment to improve the wet fastness properties of these dyes but none has proved to be totally satisfactory. Therefore, there is still a need for novel dyeing processes that improve properties in respect of application and fastness properties of the dyeings. The present work is therefore concerned with the synthesis of new cationic fixing agents and their evaluation as fixing agents in improving the wet fastness properties of anionic dyes on cellulose fibres. Eight mono-reactive (28a-d and 29a-d) and four bis-reactive (30a-b and 31a-b) 2,3-epoxy / 3- chloro-2-hydroxy propyl derivatives of quaternary ammonium chloride have been synthesised and their structures have been characterised using IR and 1H- NMR spectroscopy. Purity of these compounds has been checked by thin layer chromatography (TLC). One mono-reactive (28c) and two bis-reactive (30a and 30b) 2,3- epoxypropyl derivatives have been used for the cationisation of cellulosic iv fabrics under different pretreatment conditions. Pretreated fabrics were then dyed with a variety of direct, reactive and acid dyes under neutral and alkaline conditions in the absence of salt. A bis-reactive derivative compound 30b was also applied as an aftertreatment to the conventional direct dyeings under neutral and alkaline conditions. The reflectance values and the corresponding CIE L*, a*, b*, C* and ho colour coordinates of the samples were measured. From the reflectance values at the λ max. of the dyeings, colour strength (K/S) values of the dyeings were calculated using Kubelka-Munk equation. Fastness properties of the dyeings have been determined by following standard methods for the determination of colour fastness of textiles and leather. Pretreatment with mono- and bis-reactive cationic fixing agents (30a, 30b, 28c) has enabled the dyeing of cotton fabrics with anionic (direct, reactive and acid) dyes under neutral conditions in the absence of salt. Higher colour strength (K/S) and good wash fastness properties were obtained with the pretreated fabrics as compared to the untreated fabrics dyed with the same direct and reactive dyes. Bis-reactive derivatives showed better wet fastness properties as compared to the mono-reactive derivative. In addition, pretreatment has significantly reduced the dyeing time, thus becoming a more environmentally friendly method for the direct and reactive dyeing of cotton fabrics. Aftertreatment with cationic agents has shown a slight change in the colour of the direct dyeings but has beneficial effects on the wash fastness results.
