38. Sad/Saad
I/We begin by the Blessed Name of Allah
The Immensely Merciful to all, The Infinitely Compassionate to everyone.
38:01
a. Saad.
b. By The Divine Qur’an - full of Remembrance and Reminders.
38:02
a. They do not have any reason to reject it.
b. Instead, those who disbelieve are lost in conceit and dissent.
38:03
a. How many generations have WE destroyed before them for the same sins!
b. Then they cried out for help when it was far too late to repent and escape the punishment.
38:04
a. Yet they are surprised that a Warner should come to them from among themselves.
b. And the disbelievers say to one another:
c. ‘This Prophet is a deceiver, a liar!’
38:05
a. How ‘has he made our worshipful entities into only One worshipful entity of Allah?
b. Surely this is very astonishing and a curious thing, indeed!’
38:06
a. And the leaders among them went about saying:
b. ‘Let us go out of here.
c. And remain faithful to your worshipful entities.
d. Indeed, this is what is extremely desirable.’
38:07
a. ‘We have not heard anything like this in the religion of these later days.
b. So this concept is nothing but a fabrication.’
38:08
a. How has the Reminder - The Qur’an - been sent down on to him alone from among all of us?
b. No!
c. Instead, they are lost in doubts about MY Reminder.
d. No!
e. In fact, they have not yet tasted MY Punishment!
38:09
a. They think that no one else deserves...
The Islamic laws prevent us from the evil deeds. As well as, according to Shariah, it is permissible and sometimes even compulsory to save the believers from the actions that may lead them towards the banned activities. Therefore, the ruling of prohibition from these types of activities is called Sadd-e-Zaree’a. This is the principle extracted from the Quran and Sunnah. As Almighty Allah forbade the believers to say ‘Ra’ina’ because this word was used by Jews knowingly in a wrong manner with evil intentions, whereas, Muslims presented their requests by this same word in the highest court of The Holy Prophet (peace and blessings be upon him) for seeking easiness and relaxation in their concerned matters. As in Quran: O People who Believe, do not say (to the Prophet Mohammed- peace and blessings be upon him), " Ra’ina (Be considerate towards us)" but say, " Unzurna (Look mercifully upon us)", and listen attentively in the first place. [Baqarah 2: 104]. (To disrespect the Holy Prophet – peace and blessings be upon him – is blasphemy.) Another example by Hadith, in this regard, it is also evidenced by the good character of The Holy Prophet (peace and blessings be upon him) that sometimes He stopped himself intentionally from the permissible activities lest the common masses may involve in undesired activities on the basis of The Holy Prophet’s act. Concisely, keen consideration is required on rational basis when explaining the Shariah rulings of any matter. Otherwise, the beauty andbenefits of the Shariah may be lost. Consequently, to prevent from the future turmoil is actually the spirit of Sadd-e-Zaree’ah. As this is the actually basic need and prerequisite of Shariah. It saves and prevents its believers form expected turmoil. Therefore, if the risk of turmoil would trigger with committing the permissible activity it must be abandoned due to the risk of turmoil.
Present project focuses on the study of protease from the indigenously isolated strain Bacillus. Effects of different substrate levels, ionic concentrations (MgCl2, CaCl2, K2HPO4, (NH4)2SO4, Urea), cane molasses and yeast sludge on the production of proteases by Bacillus subtilis. Various conditions like incubation period, mode of fermentation, pH, temperature etc. were optimized. After optimization of conditions, the proteases were produced on large scale. The proteases thus produced were subjected to the purification through various steps like ammonium sulphate precipitation, ion exchange chromatography and gel filtration. Kinetic study of proteases was also carried out in order to calculate Km and Vmax of the enzymes. Thermal inactivation was studied in order to calculate the Kd, energy of activation (Ea), Gibbs free energy (∆G), Enthalpy (∆H) and entropy (∆S). Activation or inhibition effect of different metal ions and chelating agents like EDTA, EGTA and PMSF on the protease was examined. Maximum activity of the crude proteases ( 502 U) was obtained at pH 7.5, temperature 45 °C after 48 hours of continuous shaking at 220 rpm using Bacillus subtilis cultured on skim milk (2%) in the optimized medium containing MgCl2 ( 0.01%), (NH4)2SO4 (0.3%) , CaCl2 ( 0.03%), K2HPO4 ( 0.5%), yeast sludge (300 μL) and cane molasses (0.03%). Specific activity of the purified protease was (80 U/mg), yield is 3.18 % and 3 folds increase in activity. Kinetic investigation revealed that that Km and Vmax were 0.2mg/mL and 60 U/mg. Energy of activation Ea , Free energy of activation ∆G , Activaton Enthalpy ∆H, Activation entropy (∆S) were -403 KJ/mol, 91.4 KJ/mol, -403.37 KJ/mol and -407.80 J/mol. Thermo stabilization of proteases is mostly accompanied by a decrease in ∆H and ∆S. A metal ions effect on the activity of the proteases was also studied. PMSF inhibited the enzyme activity, but EDTA and EGTA would not had much pronounced effect on the activity of enzyme. That proved the class of proteases to be the serine due to the inhibition of PMSF. It was concluded that Bacillus subtilis had significant potential for the production of proteases. With respect to the kinetic study of proteases, small vales of Km than the substrate concentration showed large affinity of the enzyme with the substrate and found good source of for the production on proteases on large scale. The nature of the reaction mechanism was found to be first order because [S] was much less than Km. Activation enthalpy had negative values indicates that the enzyme was of endothermic nature. Economically cheaper metals enhanced the enzyme activity. So the Bacillus subtilis was found good catalytic agent for the production of proteases.
